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 the simplest form.
To find how many pints of strawberries Ricardo used for jam, we need to find 4/5 of 3 1/2 pints.
To find 4/5 of 3 1/2, we first need to change the mixed number to an improper fraction.
3 1/2 = 7/2
Now, we multiply 4/5 by 7/2 to find the answer.
4/5 * 7/2 = (4*7)/(5*2) = 28/10 = 2 8/10
The simplest form of this mixed number is 2 4/5.
Ricardo used 2 4/5 pints of strawberries for the jam.
