Question

Add the following mixed numbers 2 3/8+7 1/2

Answer 1

9 7/8

Explanation:

First you have to add the 2 and 7, that is 9. Then you are left with 3/8 + 1/2. You have to make them have a common denominator in order to add them. So I would multiply 1/2 by 4. 1 x 4= 4 and 2 times 4 is equal to 8 so. 1/2 is the same as 4/8. Now you can add 3/8 and 4/8 (Keep the denominator the same number and add the numerator). which equals 7/8. So the full answer now is 9 7/8. Hopefully that helped.
