Which is greater, less than, or equal to. 6 pints is _______ 60 fluid ounces
Liono4ka [1.6K]
The answer is 6 pints equal to more than 60 fluid ounces

1 pint = 16 ounces.
6 pints = x

Use the proportion:
1 pint : 16 ounces = 6 pints : x
x = 16 ounces * 6 pints : 1 pint
x = 96 ounces

6 pints = 96 ounces > 60 ounces
Therefore, 6 pints equal to more than 60 fluid ounces
