The table shows the cards in a card

game. Notice that 24 out of the 108

cards are yellow.

Heart | 24 |

Yellow | 24 |

Purple | 24 |

Green | 24 |

Wild Draw | 10 |

Extra Cards | 2 |

You can compare these two numbers

by using a ratio. Recall that the ratio

that compares 24 to 108 can be

written in several ways.

24 to 108

24:108

24 out of 108

\(\frac{24}{108} \)

A common way to express a ratio

is as a fraction in simplest form.

\(\frac{24}{108}=\frac{2}{9}\)

So, \(\frac{2}{9}\) of the cards are yellow.

The ratio can also be expressed as 2 to 9, 2:9, or 2 out of 9.

If the two quantities that you are comparing have different units of

measure, the ratio is called a rate. For example \(\frac{180 miles}{3 hours}\) compares the

number of miles traveled to the number of hours the trip took.
