Trick for finding 15 percent of any number
1. Choose a 2-digit number.
2. Multiply the number by 3.
3. Divide by 2.
4. Move the decimal point one place to the left.
Example:
1. If the number selected is 43:
2. Multiply by 3: 3 × 43 = 129
3. Divide by 2: 129/2 = 64.5
4. Move the decimal point one place to the left: 6.45
5. So 15% of 43 = 6.45.
See the pattern
1. If the number selected is 72:
2. Multiply by 3: 3 × 72 = 216
3. Divide by 2: 216/2 = 108
4. Move the decimal point one place to the left: 10.8
5. So 15% of 72 = 10.8.
Trick for finding 20 percent of any number
1. Choose a 2-digit number.
2. Divide the number by 5.
Example:
1. If the number selected is 38:
2. Divide by 5: 38/5 = 7.6
3. So 20% of 38 = 7.6.
See the pattern
1. If the number selected is 74:
2. Divide by 5: 74/5 = 14.8
3. So 20% of 74 = 14.8.
