Question

A recipe that yields two loaves of bread requires 2 1/2 cups of flour. Edgar has a bag that contains 18 3/4 cup of flour. How many cups of flour will be left in the bag if Edgar follows the recipe and makes six loaves of bread? Show your work please!

Answer 1

Since two loaves of bread need 2 1/2 cups of flour, then how many cups do six loaves need?
since 2 * 3 = 6, then the amount of flour for two loaves multiplied by 3 will be the amount needed for six!
2 1/2 * 3 = 7 1/2
Now, to find the amount of flour left over, all you need to do is subtract 7 1/2 from the amount of flour in the bag!

18 3/4 - 7 1/2 = 11 1/4 cups!
