Answer: 8 cookies per cup of sugar
============================================================
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 [tex]3.75 \text{ cups} : 30 \text{ cookies}[/tex] becomes [tex]1 \text{ cup} : 8 \text{ cookies}[/tex]
In other words, we can make 8 cookies with 1 cup of sugar.
Therefore, the unit rate is 8 cookies per cup of sugar.
