Activity

Show 10% as10/100 on a deci-mat. Discuss why it equals 0.1.

The students do examples from Material Master 4–28.

Discuss the answers in class. In particular discuss why a number like 0.05 means and equals 5%. Extend this to problems like 15% = 15/100 = 0.15. The students continue with examples from Material Master 4–28.
