Answer 4

do you know how to cross multiply ??

Answer 5

yes i got 1/2

Answer 6

ok, lets do it together, you have

14 7
----- x = -------
3 3

Answer 7

that is after it is multiplied, now you have to isolate x, so you need to multiply both sides by 3/14

Answer 8

what do you get

Answer 9

4 2/3 = 14/3
2 1/3 = 7/3

(14/3)/1 = (7/3)/x -- 14/3 to 1 cup = 7/3 to x cups)
cross multiply
(14/3)(x) = (7/3)(1)
14/3x = 7/3 (now divide both sides by 14/3 to get x by itself)
x = (7/3)/(14/3)
x = 7/3 * 3/14
x = 21/42 = 1/2
lets check..
(14/3)/1 = (7/3)/(1/2)
cross multiply
14/3 = (7/3)(2/1)
14/3 = 14/3 (correct)
ANSWER : If 2 1/3 cups of sugar is used, then 1/2 cups of chocolate chips are used.
