Question

Mary has 2/5 cups of flour, 1/4 cup of sugar 1/2 cups of baking powder. How much ingredients does mary have all together

​

Answer 1

First, get every thing to a common denominator in which case this is 20, so 2/5 would turn into 8/20, 1/4 would be 5/20, 1/2 would be 10/20. Then combine like terms and simplify. 23/20= 1 3/20
