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 1 cup

10 pounds of flour.

Step-by-step explanation:

1/4 cup of sugar is used with 2 1/2 pounds of flour.

1    cup    2 1/2 /  1/4

= 2 1/2 * 4  = 10 pounds of flour.

10 pounds

Step-by-step explanation:

We can solve this using proportion

2 1/2 pounds = 1/4 cups

x = 1 cups

we change 2 1/2 to improper fractions => 5/2

5/2 pounds = 1/4 cups

x = 1 cups

cross multiply

5/2 = 1/4 x

5/2 = x / 4

cross multiply

2x = 20

Divide bothside by 2

2x/2 = 20/2

x = 10

Therefore 10 pounds of flour is use for 1 cup
