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

The answer is 42

Step-by-step explanation:

I might be doing this wrong, but if we multiply 40 by 30 to find the total area of the country (1,200 square miles), we can divide the total population (50,000) by each answer choice to find which answer is correct; 50,000/42 is equal to 1,190, the closest product to 1,200. I claim to have possibly done this wrong, but 42 was the correct answer I received on the quiz -- hope I helped!
