Question

Emilia added the fractions 1 2/3 and 2 5/7 and got a sum of 3 7/10 . What mistake did Emilia make? What is the correct sum?

I ALL READY KNOW WHAT THE SUM IS, I JUST NEED TO KNOW WHAT MISTAKE SHE MADE.

Answer 1

Emilia added the two denominators

Answer 2

The mistake is that Emilia added the denominators of the fractions too. She's supposed to find the common denominator and then add the fractions.
