To find the amount of strawberries Ricardo used for the jam, we need to multiply the number of pints he picked (3 1/2) by the fraction representing the amount he used (4/5).
First, we need to convert the mixed number 3 1/2 to an improper fraction. This can be done by multiplying the whole number (3) by the denominator of the fraction (2) and adding the result to the numerator of the fraction (1):
3 * 2 + 1 = 7.
So, 3 1/2 is equivalent to 7/2 as an improper fraction.
Now, we can multiply 7/2 by 4/5:
(7/2) * (4/5) = (7 * 4) / (2 * 5) = 28/10.
To simplify this fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2:
28/10 = (28/2) / (10/2) = 14/5.
Therefore, Ricardo used 14/5 pints of strawberries for the jam.
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)
