To find how many pints of strawberries he used for the jam, we need to multiply the total amount of strawberries Ricardo picked (8 1/2 pints) by the fraction of strawberries he used for the jam.

The fraction representing the strawberries used for the jam is given as a denominator of 10, which means he used 10 parts out of 10 parts.

8 1/2 * 10/10 = 85/10

Simplifying the result, we divide the numerator (85) by the denominator (10):

85 รท 10 = 8 remainder 5

Therefore, the answer is:
8 5/10 or simplified to 8 1/2 pints of strawberries used for the jam.
