1. The car used 3 gallons of gas to travel 175 miles. January 30, 2012 -Create the ratios within your groups -Raise your hand quietly when your group is finished. 1. The car used 3 gallons of gas to travel 175 miles.

2. The car traveled 175 miles with 3 gallons of gas.

1. The pool filled at a rate of 12.7 gallons per minute.

1. The pool drained at a rate of 1 kiloliter per 12.7 seconds.

Proportions compare two rates or ratios Let’s see if you can create some proportions

The car used 3 gallons of gas to travel 175 miles. How many gallons will the car use to travel 300 miles?

How many miles can the car travel with 10 gallons of gas? 2. The car traveled 175 miles with 3 gallons of gas. How many miles can the car travel with 10 gallons of gas?

How many gallons full will the pool be in 10 minutes? 1. The pool filled at a rate of 12.7 gallons per minute. How many gallons full will the pool be in 10 minutes?

How many seconds will it take for the pool to have 300 KL? 1. The pool drained at a rate of 1 kiloliter per 12.7 seconds. How many seconds will it take for the pool to have 300 KL?

When two rates or ratios Are proportional, Cross Products Will be equal. Use this knowledge to solve The missing part Of the rate or ratio!

175 3 1 12.7

= 300 = x 10
