do you understand how it is set up, though?
pooja195
  • pooja195
Is there a specific question that you have that you need help on ?
anonymous
  • anonymous
i know your supposed to take the first number and put it as numerator and take second number as denominator, reduce, and change to decimal... but confused on how to go about that. and no i dont have a specific question i just want to know how to do it so i can do it on my own.

Try this 24 is what percent of 32?
phi
  • phi
you can translate A is what percent of B?" to A= x% * B (the is means equals, the % of B means multiply times B)
anonymous
  • anonymous
okay, with this set up, ignore the decimal for now. if you set it up as is over of, you cross-multiply the "fractions", then divide to isolate x to find the value of the missing number
anonymous
  • anonymous
i think it would be 24/32 then reduced to 12/16 then 6/8 and then 3/4...
anonymous
  • anonymous
going with pooja's problem :l
pooja195
  • pooja195
No thats incorrect... we need to make it a fraction or division problem all we need to do is 24/32 and you would divide it
anonymous
  • anonymous
so .75? and im guessing it would be 75% as the answer?
anonymous
  • anonymous
24/32 = x/100
anonymous
  • anonymous
75/100?
anonymous
  • anonymous
;-;
anonymous
  • anonymous
kody, you're making it more complex than it needs to be
anonymous
  • anonymous
/).- k...
anonymous
  • anonymous
how does i makes it less complex then? ;-;
anonymous
  • anonymous
this is just what im going from out of the book.
anonymous
  • anonymous
24/32 = x/100 is the values plugged into the formula. this is how the problem is set up
anonymous
  • anonymous
is this part clear?
anonymous
  • anonymous
yeah i guess :l
anonymous
  • anonymous
you then multiply the first numerator (top) by the second denominator (bottom). and the same with the first denominator and second numerator
anonymous
  • anonymous
sooo 24*32?
anonymous
  • anonymous
no. that would be the first numerator and the first denominator
anonymous
  • anonymous
OH OH OK i sees now
anonymous
  • anonymous
so i multiply diagonally? ;l so 24*100...???
anonymous
  • anonymous
yes :)
anonymous
  • anonymous
and 32 by x
anonymous
  • anonymous
but whats the x? /).-
anonymous
  • anonymous
patience, young grasshopper. the lesson is not yet finished :P
anonymous
  • anonymous
the x would be the 2400?
anonymous
  • anonymous
the equation should now look like (because you multiplied x by 32) 32x = 2400 (from multiplying 24 by 100). then, you need to isolate the x. you do this by dividing both sides by 32
anonymous
  • anonymous
/)o_o(\ big words
anonymous
  • anonymous
ummmm
anonymous
  • anonymous
equation is a math problem with an equal sign. isolate means to make alone
anonymous
  • anonymous
k.
anonymous
  • anonymous
so i divide 2400 by 32?
anonymous
  • anonymous
yes
anonymous
  • anonymous
ohkai
anonymous
  • anonymous
75 ;-;
anonymous
  • anonymous
oh so its 75% YAI IM DONE RITE?
anonymous
  • anonymous
the answer, 75% was never wrong. just how you were trying to find it
anonymous

All percent problems come down to solving this equation: $$\Huge\frac{x}{100}=\frac{a}{b}$$
anonymous
  • anonymous
the method you were trying only works on a perfect fraction. something that divides together. what if i'd asked 22 is what percent of 23?
anonymous
  • anonymous
ohohohohoho ok :3 ty vry much
anonymous
  • anonymous
i think i gots it now
anonymous
  • anonymous
okay, lets try another one just to make sure. okay?

anonymous
  • anonymous
oh sorry i had to brb. im back now
anonymous
  • anonymous
do you think you can find this?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
i know how to do that ;-;
anonymous
  • anonymous
i hope.
anonymous
  • anonymous
this one DOES work with the decimals
anonymous
  • anonymous
15.60?
anonymous
  • anonymous
yes. one more
anonymous
  • anonymous
kK
anonymous
  • anonymous
42 is 60 percent of what?
anonymous
  • anonymous
70
anonymous
  • anonymous
i tink
anonymous
  • anonymous
