Add whole numbers to whole numbers.
Add fractions to fractions
.
Regroup and
simplify
,
if needed.

Let's try it with

First, add the whole numbers.

Then, add the fractions. Add the numerators and keep the denominator the same.

Now, simplify.

So,

Add and subtract mixed numbers with like denominators

Adding mixed numbers with unlike denominators

To add mixed numbers with different denominators, follow these steps:

Rename the fractions using a common denominator.
Add whole numbers to whole numbers.
Add fractions to fractions
.
Regroup and simplify, if needed.

Let's try it with

First, rename the fractions using a common denominator. The

least common denominator

of these fractions is 10. Multiply to make

equivalent fractions

with 10 as the denominator.

Then, add the whole numbers.

Now, add the fractions. Add the numerators and keep the denominator the same.

This answer is already in simplest form, so there is no need to regroup or simplify.

So,
