Question

Megan consumed 3.5 gallons of water in one day. How many milliliters are equal to 3.5 gallons, if 1 liter equals 1,000 milliliters and 1 gallon = 3.785 liters?

Answer 1

First, find how many milliliters there are in 1 gallon. 3.785 x 1,000 = 3,785
There are 3,785 milliliters in one gallon.

Then, multiply that by 3.5    3,785 x 3.5 = 13,247.5   

There are 13,247.5 ml in 3.5 gallons
