let's define our variables first let T = the number of cookies terri has let J = the number of cookies jennifer has with me so far?

I'm back lol ok, so they have 480 cookies altogether, then T + J = 480, with me so far?
anonymous
  • anonymous
yes!
Vocaloid
  • Vocaloid
it also says that terri has 1 2/3 as many cookies as jennifer to make things easier, I'm going to rewrite 1 2/3 as 5/3, since these two fractions are equal so T = (5/3)J, with me so far?
anonymous
  • anonymous
yes!
Vocaloid
  • Vocaloid
great, now we can replace "T" with "5/3 J" so T + J = 480 becomes J + (5/3)J = 480 know where to go from here?
anonymous
  • anonymous
would you do 2j x 5/3= whatever
Vocaloid
  • Vocaloid
where are you getting 2 from
Vocaloid
  • Vocaloid
start by adding J + (5/3)J = ?
anonymous
  • anonymous
combining the 2 js
Vocaloid
  • Vocaloid
uh not quite 1 + (5/3) = ?

2 2/3
Vocaloid
  • Vocaloid
good, we can also write 2 2/3 as 8/3 now we have J + (5/3)J = (8/3)J so (8/3)J = 480 know where to go from here?
anonymous
  • anonymous
@Vocaloid i feel as if you are a genius
anonymous
  • anonymous
no kidding
anonymous
  • anonymous
divide 8/3 on both sides
Vocaloid
  • Vocaloid
yup so 480/(8/3) = ?
anonymous
  • anonymous
20?
Vocaloid
  • Vocaloid
hmmm not quite when we divide by a fraction, we can flip the fraction and multiply so 480/(8/3) becomes 480*(3/8) which equals...?
anonymous
  • anonymous
180
Vocaloid
  • Vocaloid
ahaha that's nice of you guys to say, I'm far from a genius though
Vocaloid
  • Vocaloid
and yes 180 is the answer, good job~
anonymous
  • anonymous

Vocaloid
  • Vocaloid
