Challenge 3

Find 10% of the following amounts: 1. 2. 3.

10% of 30 = 10% of 90 = 10% of 60 =

4. 5. 6.

10% of 20 = 10% of 100 = 10% of 70 =

4. 5. 6.

20% of 20 = 20% of 100 = 20% of 70 =

4. 5. 6.

30% of 20 = 30% of 100 = 30% of 70 =

4. 5. 6.

5% of 20 = 5% of 100 = 5% of 70 =

4. 5. 6.

15% of 20 = 15% of 100 = 15% of 70 =

Now find 20%: 1. 2. 3.

20% of 30 = 20% of 90 = 20% of 60 =

Now find 30%: 1. 2. 3.

30% of 30 = 30% of 90 = 30% of 60 =

Now find 5%: 1. 2. 3.

5% of 30 = 5% of 90 = 5% of 60 =

Finally find 15%: 1. 2.

3.

15% of 30 = 15% of 90 = 15% of 60 =
