To find out how many gallons the family will drink in 15 days, we need to determine their rate of milk consumption per day.
The family drinks 2 gallons of milk in 3 days, so they drink 2/3 = <<2/3=0.6666666666666666>>0.67 gallons of milk per day.
Therefore, in 15 days, the family will drink 0.67 x 15 = <<0.67*15=10.05>>10.05 gallons of milk.
The family will drink approximately 10.05 gallons of milk in 15 days.
a family drinks 2 gallons of milk in 3 days. at that rate, how many gallons will the family drink in 15 days?
