Using a Calculator: Activity 1 of 3

To figure out percentages with a calculator, use the multiplication function.

First, convert the percentage to a decimal:

A percentage is something out of 100, so 25% equals 25/100, which equals 0.25

For one-number percentages, add a zero after the decimal point. So, 8% is 0.08 and 5% is 0.05

What’s 10% of 60?  

1. Convert 10% to 0.10 
2. Multiply 60 by 0.10 (60 × 0.10) 
3. The answer is 6

Use a calculator to fill in the blank with the correct answer.
