Question

3 3/4 cups of sugar are needed to make 30 cookies. Write the unit rate for the number of cookies that can be made per each cup of sugar

Answer 1

Answer: 8 cookies per cup of sugar

============================================================

Step-by-step explanation:

3/4 = 0.75

3 & 3/4 = 3 + 3/4 = 3 + 0.75 = 3.75

The mixed number 3 & 3/4 is the same as the decimal value 3.75

We need 3.75 cups of sugar to make 30 cookies.

Dividing both of those values by 3.75 will tell us how many cookies we can make with 1 cup of sugar.

• (3.75)/(3.75) = 1
• 30/(3.75) = 8

This means the ratio
`3.75 \text{ cups} : 30 \text{ cookies}` becomes
`1 \text{ cup} : 8 \text{ cookies}`

In other words, we can make 8 cookies with 1 cup of sugar.

Therefore, the unit rate is 8 cookies per cup of sugar.
