How do you add a mix number by a mix number?

Answer 1

There are two methods:

1) convert both the numbers into improper fractions, change the denominator so they both are the same (remembering to change the numerator by the corresponding amount also), then add them together. You can change the answer back to a mixed number if you want to.

For example: 1 1/2 + 3 3/4 = 3/2 + 15/4 = 6/4 + 15/4 = 21/4 = 5 1/4

2) add the first part of the numbers together, then change just the fraction so that they have matching denominator (once again making sure the numerator is multiplied by the same amount) and then adding the fraction onto the number (changing the fractions total into mixed number if you have to)

For example: 1 1/2 + 3 3/4 = 4 + 1/2 + 3/4 = 4 + 2/4 +3/4 = 4 + 5/4 =

4 + 1 1/4 = 5 1/4
