If a gas tank can hold 60 liters of gas, copy and label the percent ruler below on your paper and use it to find how many liters are in the tank when it is:
50% is equal to one-half. What is one-half of 60 liters?
If you divide 60 liters into 10 parts, there will be 6 liters each. How many liters would there be if you had 7 of these groups?
This problem is similar to part (b). When you divide 60 liters into 5 parts, each part has 12 liters.
