Question

What is 6 qt 1 pt minus 2 qt 1 pt

Answer 1

it is 4 quarts because 1 pint each cancels each other out and 6 minus 2 is 4

Answer 2

there are 2 pints in 1 quart
so if you change the quarts to pints and then subtract then you can change your answer back to quarts and pints.

6 qt and 1pt = 13 pints
2 qt and 1 pt = 5 pints

13 - 5 = 8 pints

your answer should be 4 quarts

hope this helps :)
