9. Subtract: 5-3 1/3

Answer: 1 and 2/3

Step-by-step explanation:

Imagine 3 1/3 as if it's in parenthesis as (3 + 1/3)

Subtract three from five.

You should get two.

Then you subtract the last 1/3 from that two.

There are three thirds in one digit.

Therefore, two thirds are left over, plus that last whole digit.

You are left with one and one third.
