Understand units: Step 1: Understand the units and what needs to be subtracted.We have 8 quarts and need to subtract 4 quarts 1 pint from it.
Subtract quarts: Step 2: Subtract the quarts.8qt−4qt=4qt
Subtract pints: Step 3: Subtract the pints.Since there are no pints mentioned in the 8 quarts, we assume it to be 0 pints.0 pt−1 pt=−1 pt, which isn't possible in this context, so we need to adjust the quarts.We convert 1 quart into pints (1 qt=2 pt), so now we have:4 qt=3 qt+2 pt (after conversion)Now subtract the 1 pint:2 pt−1 pt=1 pt
