In this lesson, you used models to show how different forms of rational numbers (fractions, decimals, and percents) can be used to represent the same part of a whole.

sixty-four out of one hundred people visiting the zoo like the new giraffe exhibit

The model below shows the number of people who like the new giraffe exhibit.

sixty-four out of one hundred squares shaded

Since there are 64 squares out of 100 shaded, this ratio can be written as a fraction, decimal, or percent.

16 over 25 16 25 = 64 over 100 64 100 = 0.64 = 64%

You also investigated several different ways to generate equivalent forms of a rational number if you are given a fraction, decimal, or percent.

Interactive exercise. Assistance may be required. To review the procedures used for generating equivalent forms of rational numbers, click on the representation that you wish to generate from the representation that you know. For example, if you have a fraction and wish to generate an equivalent decimal number, click on the “Fraction → Decimal” button to see a procedure you may use.
