Maurice's gas tank can hold liters of gas. On your paper, copy and label the percent ruler below. Then use it to find how many liters are in the tank when it is:

A percent ruler scaled by 10%. Above the 0% is 0 liters. Above 100% is 60 liters.

  1. full

  1. full

  1.  full

is equal to one half. What is one half of liters?

30 L Added to the percent ruler is 30 liters under 50%.

If you divide liters into parts, there will be liters each. How many liters would there be if you had of these groups? Added to the percent ruler: 6 liters under 10%.

This problem is similar to part (b). When you divide liters into parts, each part has liters. Added to the percent ruler: 12 liters under 20%
