Write and solve a proportion showing that the ratio of sugar to chocolate chips is constant:





ANSWER: 7/3 cups, or 2 1/3 cups, of chocolate chips
Answer by Theo(13342)   (Show Source): You can put this solution on YOUR website!
s/c = 1.5/1 = 3/2
you get s/c = 3/2
from that, you get s = 3/2 * c, or c = 2/3 * s
3.5 cups of sugar is equal to 3 and 1/2 which is equal to 7/2 cups of sugar.
c = 2/3 * s becomes c = 2/3 * 7/2 = 14/6 cups of chocolae chips.
14/6 = 2 and 2/6 cups of chocolate chips.
to confirm, multiply 2 and 2/6 by 1.5 to get 3 and 3/6 which is equal to 3.5 cups of sugar.
your solution is that you would need 2 and 1/3 cups of chocolate chips, which can also be shown as 7/3 cups of chocolate chips whiich.
in decimal form, that would be equal to 2.33 cups of chocolate chips, when rounded to 2 decimal places.
