The container that holds the water for the football team is
3/10
full. After pouring in
5
gallons of water, it is
1/2
full. How many gallons can the container hold?
so since only 2/10 equals 5 gallons then you add both of the 2/10 which would equal 10 and then find out what 1/10 would equal which is 2.5 so 12.5 is half so it would hold 25 gallons
