Activities

Students can convert a decimal to a percent by multiplying the decimal by 100.  They need to enter the decimal into the calculator, with or without the leading zero, multiply by 100 and then press enter. The screenshot to the right shows how 0.23 is converted to 23%.

Discuss with students about how they can convert a fraction to a percent. They will need to combine two of the steps used in this first problem; converting first to a decimal and then multiplying the decimal by 100. 

Students explore the relationship between mixed numbers, decimals, and percents. They can enter a mixed number into the calculator by typing in the whole number, pressing "Unit," typing the numerator, arrow down to the bottom, and typing the denominator.
