A large pot holds 8 quarts of spaghetti sauce. Lisa has 1-pint containers if spaghetti sauce how much will Lisa need to fill the pot?

Conversion factor: 1 pint = 0.5 quarts or 2 pint = 1 quart

multiplying both sides by 8

8 (1 quart) = 8 (2 pints)

8 quarts = 16 pints

so she will need a total of 16 pints to fill the pot. she already has 1 so ... 16 - 1 = 15 more pints.

and looking at the 1st conversion factor 1 pint = 0.5 quarts

15 (1 pint) = 15 (0.5 quart)

15 pints = 7.5 quarts
