Ricardo picked 3 12 pints of strawberries and used 45 of them to make jam. How many pints of strawberries did he use for the jam? Write the answer as a mixed number in simplest form.

Answer 1

Ricardo picked a total of 3*12 = <<3*12=36>>36 pints of strawberries.
He used 45 pints of strawberries for the jam, so the answer is 45/36 = 1 9/12 = 1 3/4 (in simplest form). Answer: \boxed{1\frac{3}{4}}.
