Hunter had seven gallons of water in the refrigerator. Of those, two and one-fourth gallons were spring water and one and one-fifth gallons were filtered water. How many gallons of water were not spring or filtered?

3 11/20

Step-by-step explanation:

Total gallons of water=7

Spring water=two and one-fourth gallon=2 1/4

Filtered water=one and one-fifth

=1 1/5

Spring water+filtered water=2 1/4 + 1 1/5

=9/4+6/5

= 45+24/20

=69/20

=3 9/20

How many gallons of water were not spring or filtered

=Total gallons - (spring + filtered water)

=7-69/20

=140-69/20

=71/20

=3 11/20
