Q:
# Eli is making a party mix that contains pretzels and chex. For each cup of pretzels, he uses 3 cups of chex. How many cups of pretzels and how many cups of chex does he need to make 12 cups of party mix?

Accepted Solution

A:

So for every one cup of pretzels (1p)

You have three cups of chex (3c)

The ratio between pretzels and chex is 1p:3c

Thus, changes in 1 is proportional with changes in 3.

You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.

So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.

Thus the answer is 3p:9c

You have three cups of chex (3c)

The ratio between pretzels and chex is 1p:3c

Thus, changes in 1 is proportional with changes in 3.

You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.

So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.

Thus the answer is 3p:9c
