Add fractions to fractions Which are the fractions?

Multiple Choice

3/8 + 1/8 = ?

What about improper fractions?

If your numerator is bigger than your denominator you need to regroup.

- look for hidden "whole fractions" in your answer.

Regroup

In the last answer 4/5 + 3/5 = 7/5

There is a hidden "whole fraction" in there!

You can also write 7/5 as 5/5 + 2/5

Solve : 4 7/12 + 6 5/12

• 10 2/12

• 10 1/6

• 11

• 11 2/12

Did you forget to find the hidden "whole fractions?"

12/12 = 1

How about one more?

solve:

Multiple Choice

solve: 7 3/5 + 4 3/5 =

• 11

• 11 3/5

• 12 1/5

• 12

What about subtraction?

• the same steps apply

• but now you might need to borrow from the whole number...

solve

Multiple Choice

Solve: 7 2/3 - 3 1/3

• 2 2/3

• 2 1/3

• 4 2/3

• 4 1/3

That was easy

but what if you have to borrow?

How do you solve 5/8 - 7/8?

• Borrow from the whole number.

• Rewrite 4 5/8 as 3 +1 + 5/8

• Rewrite again as 3 + 8/8 + 5/8

• Regroup and you get 3 + 13/8

• or 3 13/8

• Now you can solve 3 13/8 - 2 7/8

Multiple Choice

Solve: 3 13/8 - 2 7/8

• 1 6/8

• 5 2/8

• 6/8

• 1 2/8

Multiple Choice

Now simplify: 1 6/8 in its simplest form is?

• 1 3/4

• 1 1/2

• 1 2/4

• 1 3/6

Now it's your turn:
