Question

A baker used 3/16 cup of sugar. Then she used another 1/2 cup of sugar. How much sugar did she use in all?

Answer 1

It is asking for a total, or addition, of the ingredient.

To add fractions you need common denominators. You must find the LCD, least common denominator, of 2 and 16.

LCD of 2 & 16 = 16. Now convert 1/2 into 16ths.

1/2 = 8/16

3/16 + 8/16 = 11/16 total cups.

Answer 2

10/16 cups of sugar or 5/8 cups of sugar
