**The bottom number of a fraction tells how many parts are in each whole group.**

The bottom number of this fraction is 4. The 4 tells us how many parts to make in each whole group. 4 The top number tells how many parts we use, so we shade in 3 parts. 3

Your turn. Find problem 1 of part A on your worksheet. What is the first fraction? Yes, 5 2 Divide each circle into the right number of parts. This is what you should have. Now shade the number of parts you use. This is what you should have. Check your work.

10
**Now look at problem 2 on your worksheet. 7 4**

Divide each circle in to the right number of parts. This is what you should have. Now shade the number of parts you use. This is what you should have. Check your work.
