Working Exercise from Number and Number Sense Theme

Give 3 minutes

To teach this we instruct that all practical percentage applications have three basic parts:

• Actual amount
• Base (whole or original amount)
• Rate (%)

And the idea that:
Actual amount =
Rate(%) * Base (whole amount) =
1.5% * 18 feet = 27/100 = .27 ft

Measurement conversion =
.27 feet * 12 in /1 = 3.24 inches
