Ricardo picked 3 1/2 pints of strawberries and used 4/5 of them to make jam. How many pints of strawberry did he use for the jam? Write the answer as a mixed number in the simplest form.
To find out how many pints of strawberries Ricardo used, we need to multiply the number of pints he picked by the fraction representing the fraction he used for the jam: 3 1/2 pints * 4/5 = 14/2 * 4/5 = 56/10 = <<14/2*4/5=56/10>>56/10 = 5 1/2 pints of strawberries. Answer: \boxed{5\frac{1}{2}}.
