My textbook says 13.13 so I was wondering how they got that. Can you show me/ Tell me how you got that answer because I'm kinda confused...

its easy bc its basic order of operations

juciystar234Best ResponseYou've already chosen the best response.2
Yeah I know NVM :) thanks

can i hav a medal o.O

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

asnaseerBest 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
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
Ok let me check it out hold on
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
look at the 2nd section "The standard order of operations"
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
Ok hold on hmm SO MANY WORDS!! D:

lol typical wikipedia
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
Ok I kinda got it
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
(not really so much)
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
good  so first thing to attack is the brackets
 one year ago

asnaseerBest 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
 one year ago

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

juciystar234Best ResponseYou've already chosen the best response.2
hmmm ok im confused...
 one year ago

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

asnaseerBest ResponseYou've already chosen the best response.1
now note that a(b) simply means a*b  agreed?
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so we can say that:\[5+7(0.91)=5+7*0.91\]
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
does that make sense now?
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
good  now what should the next set of operations be?
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
we have handled the brackets
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
sorry didnt mean to put >
 one year ago

asnaseerBest 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
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so what is 7 * 0.91 = ?
 one year ago

asnaseerBest 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
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
wouldnt you add? or subtract?
 one year ago

asnaseerBest 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
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
hang on a second  I think I misread your question
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
I believe it was this instead:\[8 6.2 \div 5 + 7(0.91)\]
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
ok, sorry I originally interpreted it as:\((8 6.2) \div (5 + 7(0.91))\)
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so lets start again  ok?
 one year ago

asnaseerBest 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\[8 6.2 \div 5 + 6.37\]
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so next we should do what?
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
nope  have a closer look at what is still left
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
like left to right but switch add with division
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
it should be division next
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so what is 6.2 divided by 5 = ?
 one year ago

asnaseerBest 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)

juciystar234Best ResponseYou've already chosen the best response.2
sorry i was drawing :P
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
ok :) so now how do i do it ? :
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
the /quick/ method or using long division like you attempted up there?
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
or like were did i mess up

juciystar234Best ResponseYou've already chosen the best response.2
my decimal messed me up..
 one year ago

asnaseerBest 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)
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
ok, so we now have:\[8 6.2 \div 5 + 6.37=81.24+6.37\]
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
the rest should now be straight forward
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
but be careful with the signs
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
I got this part let me draw it for you

asnaseerBest ResponseYou've already chosen the best response.1
remember the 1.24 has a minus sign next to it
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so this is really "1.24 + 6.37"
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
no thats not a negative its a minus
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
so it might be better to first do "8  1.24"
 one year ago

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

asnaseerBest ResponseYou've already chosen the best response.1
I was trying to explain why you had to do "1.24 + 6.37" previously
 one year ago

juciystar234Best 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!!!!!
 one year ago

asnaseerBest ResponseYou've already chosen the best response.1
yes  that is the correct answer
 one year ago

juciystar234Best ResponseYou've already chosen the best response.2
Thanks once again!! :D
