Mixed Numbers

Pick two numbers with different denominators to mentally add together.

Open Ended

Which mixed number should we change to make them both have the same denominator?

Why?

Answer

We only need to change the 2 1/5.

Math Notebook

Change 2 1/5 to have the same denominator as 1 3/10.

What is our new mixed number?

Changing 2 1/5 makes sense because we just need to double to make a denominator of 10.

If we tried to change 1 3/10, we would need to half the denominator to make it 5, and that makes it harder to work with.
