Answer:
3 1/3 gallons
Explanation:
There are 20 gallons and 6 families. We want to divide the 20 gallons equally amongst the 6 families. The key word here is "divide". We want to use division:
20 gallons รท 6 families = 20/6 gallon per family = 10/3 gallons per family
= 3
gallons per family
Thus, each family got 3 1/3 gallons.
Hope this helps!
