figuring multipication with gallons and quarts?

Tommy -- please post your problem. Your "question" doesn't make any sense as you posted it.

Jay has 19 quarts of paint for the outside of his barn than for inside. If he uses 107 quarts in all, how many gallons of paint will be used to paint the inside of the barn?

To figure out multiplication with gallons and quarts, you'll need to understand the conversion between these two units of volume.

1 gallon is equal to 4 quarts. Therefore, when multiplying gallons and quarts, you can consider 1 gallon as 4 quarts.

Here's an example to help explain:

Question: How many quarts are there in 3 gallons?

Solution:
Since 1 gallon is equal to 4 quarts, you can multiply 3 gallons by 4 quarts/gallon to find the answer.

3 gallons * 4 quarts/gallon = 12 quarts

So, there are 12 quarts in 3 gallons.

In summary, to figure multiplication with gallons and quarts, you need to remember that 1 gallon is equal to 4 quarts and use this conversion factor in your calculations.
