Example If a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2 over 1/4 miles per hour, equivalently 2 miles per hour.

A ratio is just a comparison of two things using numbers. If you want to compare two different quantities it is important to use a ratio to compare it.

What are some examples? Writing Ratios: X:Y x/y X to y

Example Sally has 10 toys. She has 7 dolls and the rest are stuffed animals. What is the ratio of dolls to stuffed animals?

A trail mix recipe calls for 1/3 pound of mixed nuts, 4/15 pound of raisins, and 2/5 pounds of granola. What is the ratio of raisins to mixed nuts in simplest form?

Franklin walked 12 mile in 812 minutes. What is the unit rate in miles per minute?

Molly runs 13 of a mile in 4 minutes. If Molly continues at the same speed, how long will it take her to run one mile? Draw and label a picture showing why your answer to part (a) makes sense.
