Answer:
b/f = 2/5
5b = 2f
Step-by-step explanation:
Loaves of bread = b
Cups of flour = f
She uses 7 1/2 cups of flour to make 3 loaves of bread.
Cups of flour = 7 1/2
Loaves of bread = 3
The relationship between b and f
b/f = 3÷7 1/2
b/f = 3 ÷ 15/2
b/f = 3 × 2/15
b/f = 6/15
b/f = 2/5
b = 2/5f
b = 2f/5
5b = 2f
