Question

Priya has a recipe for banana bread. She uses 7/1/2 cups of flour to make 3 loaves of banana bread. Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour. Which of these equations represents the relationship between b and f?

Answer 1

5b = 12f

Explanation:

Answer 2

5b=2f

Explanation:

Priya uses
`7(1)/(2)` cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

`\frac{\text{cups of flour}}{\text{loaves of banana bread}}=(7 (1)/(2))/(3)\\\\=((15)/(2))/(3)\\\\=(15)/(2)* (1)/(3)\\\\=(5)/(2)`

It means,

`(f)/(b)=(5)/(2)\\\\5b=2f`

So, the relationship between b and f is "5b=2f".
