d. 10

1 answer

b. 5/8

To find how many cups of flour are needed for 1 cup of sugar, we can set up the ratio: 2 1/2 cups of flour / 1/4 cup of sugar.

First, simplify the ratio:
2 1/2 = 5/2
1/4 = 1/4

Now, divide the cups of flour by the cups of sugar:
(5/2) รท (1/4) = (5/2) x (4/1) = 20/2 = 10

So, Eric should use 10 cups of flour for 1 cup of sugar. To convert this to pounds, you would need to know the weight of 1 cup of flour which is approximately 0.5 pounds. So, Eric should use 5 pounds of flour for 1 cup of sugar.
