Billy made 5 gallons of juice for a picnic. He said that he made
5
4 quarts of juice.

Complete the explanation of Billy's mistake.

Billy the number of gallons by 4 to convert to quarts.

He should have the number of gallons by
to find the number of quarts in 5 gallons.

There are
quarts in 5 gallons of juice.

Respuesta :

The answer is 20.  Here is why: there are 4 quarts in 1 gallon and you want to know how many there are in 5.  So you multiply 4 by 5 and you get 20 quarts. 
Hope this helped a lot. ;-)
