Make the denominators equal
4 9/12 + 2 10/12
Add the fractions
6 19/12
Simplify
7 7/12
Marianne completed 2/10 and Arlene 3/10 so that’s 5/10 which means you and Tyler did 5/10 if you divide that by 2 it’s 5/20 I think but I don’t really understand as the possible answers aren’t fractions? Hopefully that’s right haha
You are right on the question
