Matt buys 14 jars of paint. Each jar contains 300 milliliters of paint.

How many liters of paint in all is there in the jars?

4.2 L

42 L

420 L

4,200 L

4.2 L.

If you multiply 14 by 300 you will get the total amount of mililiters for all the jars, which is 4,200. There are 1,000 mililiters in a liter, so if you divide 4,200 by 1,000 you get 4.2.
