for this:\[\frac{8 6.2}{5 + 7(0.91)}\] you need to follow BODMAS  have you heard about that?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
it is known by other names as well, see here: http://en.wikipedia.org/wiki/Order_of_operations

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Ok let me check it out hold on
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
look at the 2nd section "The standard order of operations"

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Ok hold on hmm SO MANY WORDS!! D:

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Ok I kinda got it

kwl i hope u pass :)

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
good  so first thing to attack is the brackets
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Thanks
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
in this case the brackets just contain a number  so no actual operation to perform inside the brackets
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
we can therefore remove the brackets to end up with:\[\frac{8 6.2}{5 + 7(0.91)}=\frac{8 6.2}{5 + 7*0.91}\]
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Mhm ok
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
hmmm ok im confused...
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
lets jus concentrate on the denominator for now, we had:\[5+7(0.91)\]correct?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
now note that a(b) simply means a*b  agreed?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
agreed
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so we can say that:\[5+7(0.91)=5+7*0.91\]
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
does that make sense now?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
ok got tht
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
good  now what should the next set of operations be?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
we have handled the brackets
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
um to multiply?>
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
sorry didnt mean to put >
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
it should be exponents and roots next  but you do not have any here so we go to the next one: multiplication an division
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Yea!! Ok
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so what is 7 * 0.91 = ?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Um hold on
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
correct, so now we end up with:\[\frac{8 6.2}{5 + 7(0.91)}=\frac{8 6.2}{5 + 7*0.91}=\frac{8 6.2}{5 + 6.37}\]now most people get confused here because they think the next thing to do is the division
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
wouldnt you add? or subtract?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
but what you need to remember is that you go through BODMAS for the numerator and the denominator seperately
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
hang on a second  I think I misread your question
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
I believe it was this instead:\[8 6.2 \div 5 + 7(0.91)\]
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
am I right?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
ok, sorry I originally interpreted it as:\((8 6.2) \div (5 + 7(0.91))\)
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
ohhh ok
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so lets start again  ok?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
\[8 6.2 \div 5 + 7(0.91)\]first step  brackets to get:\[8 6.2 \div 5 + 7(0.91)=8 6.2 \div 5 + 7*0.91\]next is exponents/root but we have none next is multiplication/division  we have both, so you did 7*0.91 = 6.37\[8 6.2 \div 5 + 6.37\]
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
thats how far we got
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so next we should do what?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
or no subtract
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
nope  have a closer look at what is still left
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
like left to right but switch add with division
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
it should be division next
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
so divide?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so what is 6.2 divided by 5 = ?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
ok hold on
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
(a quick trick to divide by 5 is to divide by 10 and then halve the result)

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
sorry i was drawing :P
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
that is not correct
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
ok :) so now how do i do it ? :
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
the /quick/ method or using long division like you attempted up there?
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
or like were did i mess up
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
um i guess....

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
i get it!!!
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
my decimal messed me up..
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
the other way is 6.2 divided by 10 is 0.62 double that is 0.62 + 0.62 = 1.24 (sorry I incorrectly stated you halve the result up there  it should be double the result after dividing by 10)
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Hmmm ok
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
ok, so we now have:\[8 6.2 \div 5 + 6.37=81.24+6.37\]
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
the rest should now be straight forward
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
so adding?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
but be careful with the signs
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
I got this part let me draw it for you

 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
remember the 1.24 has a minus sign next to it
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so this is really "1.24 + 6.37"
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
no thats not a negative its a minus
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
so it might be better to first do "8  1.24"
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
then add
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
think of it in this way:\[8 6.2 \div 5 + 6.37=81.24+6.37=8+(1.24)+6.37\]
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
yes add next
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
ok so 13.13
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
I was trying to explain why you had to do "1.24 + 6.37" previously
 2 years ago

juciystar234 Group TitleBest ResponseYou've already chosen the best response.2
Yaaa i got it my text book says that but i needed to work it out thank you!!!!!
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
yes  that is the correct answer
 2 years ago
