Ricardo picked 8 1/2 pints of strawberries and used 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.

Question

28/10

2 4/5

2 8/5

2 8/10

Answer 1

To find the answer, we need to multiply 8 1/2 by 2/10.

To convert the mixed number 8 1/2 to an improper fraction, we multiply the whole number (8) by the denominator (2), and add the numerator (1). This gives us a new numerator of 17. The denominator remains the same (2). So 8 1/2 can be written as 17/2.

Multiplying 17/2 by 2/10 gives us (17 * 2) / (2 * 10) = 34/20.

To simplify a fraction, we find the greatest common divisor (GCD) of the numerator and denominator and divide both by that number. The GCD of 34 and 20 is 2. Dividing both by 2 gives us 17/10.

Therefore, Ricardo used 17/10 pints of strawberries for the jam. In simplest form, this is written as 1 7/10.
