Ricardo picked 3 1/2 pints of strawberries and used 4/5 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.(1 point)

Ricardo used 4/5 of the strawberries, which is equal to (4/5)*(7/2) = 28/10 = <<(4/5)*(7/2)=28/10=2.8>>2.8 pints of strawberries. In simplest form, this is 2 4/5 pints. Answer: \boxed{2\frac{4}{5}}.
