Question

Mary has a recipe for cranberry bread. she uses 6 and 2/3 cups of flour to make 2 loaves of cranberry bread.

Sue will follow the same recipe. She will make b loaves of cranberry bread using f cups of flour.


Which of these equations represents the relationship between b and f?


1. b= 3/7 f


2. b= 7/3 f


3. b= 3/10 f


4. b= 10/3 f

Answer 1

The correct equation representing the relationship between the number of loaves of cranberry bread (b) and cups of flour (f) is b = 10/3 f, based on Mary's recipe ratio.

Step-by-step explanation:

Let's find the correct relationship between b loaves and f cups of flour based on Mary's recipe. According to the information provided, Mary uses 6 and 2/3 cups of flour to make 2 loaves of cranberry bread. This means that the ratio of cups to loaves is 6.67/2, which simplifies to 20/6.

We can set up a proportion to find the relationship where f is proportional to b. This gives us the equation f / b = 20/6, or after multiplying both sides by b, we get f = (20/6) * b. Simplifying this fraction gives us f = (10/3) * b, which matches option 4.

Therefore, the correct equation that represents the relationship between b and f is b = 10/3 f.
