What is 1 and a half plus 1 quarter?

Answer 1

First, find a common denominator. 1 is the same as 4/4. A half is the same as 2/4. And 1 quarter (.25) is the same as 1/4. So, since they are now all over a denominator of four, simply add the numerators and reduce. 4+2+1=7. 7/4 is your answer, or 1 3/4.
