Question

Work out the product of 1 5/7 and 3 1/4 Give your answer as a mixed number.

Answer 1

Answer: 5 4/7

Step-by-step explanation: First, we need to change both 1 5/7 and 3 1/4 into an improper fraction. So:

`1 (5)/(7)` =
`(12)/(7)`

`3(1)/(4)` =
`(13)/(4)`

So, now we need to cross-multiply 12/7 and 13/4.

That'd be 156/28

But wait. We analyze that 156 and 28 can be reduced by 4

So, 156 divided by 4 is 39, and 28 divided by 4 is 7. So now our improper fraction is 39/7. To make it an improper fraction, we divide 39 by 7, which would give us 5 4/7. I hope this helped!
