Question

Marie added 3 1/8 cup of all-purpose flour and 1/4 cup of whole wheat flour in the cake. She added 1/3 cup of sugar at also, how much flour she added in the cake ?

Answer 1

3
`(3)/(8)`

Explanation:

Maria only combined two different types of flour to the cake. Therefore, in order to find the total amount of flour she added we need to add these measurements together. First, we need to find a common denominator. We do this by multiplying the numerator and denominator of the amount of whole wheat flour by 2. This would be the easiest way of giving us the same denominator as the measurement for the all-purpose flour.

`(1 * 2)/(4 * 2)` =
`(2)/(8)`

Now that we have the same denominators we can simply add both measurements together

3
`(1)/(8)` +
`(2)/(8)` = 3
`(3)/(8)`
