Question

Paul filled pint containers with 440 cups of water. How many pint containers did Paul need? 1 pint = 2 cups

Answer 1

For this case we can make the following rule of three:
 1pint ------> 2cups
 x -----------> 440 cups
 Clearing x we have:
 x = (440/2) * (1)
 x = 220 pint containers.
 Answer:
 Paul needs about:
 x = 220 pint containers.

Answer 2

Paul would have 220 pint containers!

440/2 =220

Because 1 pint = 2 cups
