Question

Eric is baking a cake. The recipe calls for 2 1/2

pounds of flour for every

1/4 cup of sugar. How many pounds of flour should Eric use for cup of sugar?

Answer 1

To find out how many pounds of flour Eric should use for 1 cup of sugar, we need to set up a proportion.

Since the recipe calls for 2 1/2 pounds of flour for every 1/4 cup of sugar, we can write the proportion as:

2.5 pounds of flour / 0.25 cup of sugar = x pounds of flour / 1 cup of sugar

To solve for x, we can cross multiply:

0.25x = 2.5

Dividing both sides of the equation by 0.25:

x = 2.5 / 0.25

x = 10

Therefore, Eric should use 10 pounds of flour for 1 cup of sugar.
