The total of the following numbers 8 5/8, 6 1/4, 7 3/16, and 5 1/4 is?

Explanation:
When adding mixed numbers, add the fractional parts with a common denominator and then combine the whole parts, carrying over when the fractions sum to a whole or more. Convert to sixteenths to keep things consistent: 8 5/8 = 8 10/16, 6 1/4 = 6 4/16, 7 3/16 = 7 3/16, 5 1/4 = 5 4/16. Add the fractional parts: 10/16 + 4/16 + 3/16 + 4/16 = 21/16, which is 1 plus 5/16. Carry the 1 to the whole numbers. Add the whole numbers: 8 + 6 + 7 + 5 = 26, plus the carried 1 equals 27. So the total is 27 5/16.

When adding mixed numbers, add the fractional parts with a common denominator and then combine the whole parts, carrying over when the fractions sum to a whole or more.

Convert to sixteenths to keep things consistent:

8 5/8 = 8 10/16,

6 1/4 = 6 4/16,

7 3/16 = 7 3/16,

5 1/4 = 5 4/16.

Add the fractional parts: 10/16 + 4/16 + 3/16 + 4/16 = 21/16, which is 1 plus 5/16. Carry the 1 to the whole numbers.

Add the whole numbers: 8 + 6 + 7 + 5 = 26, plus the carried 1 equals 27.

So the total is 27 5/16.
