Question

Marianne, Arlene, Tyler, and I worked together to complete a group project. Marianne completed 1/5 of the project. Arlene completed 3/10 of the project. Tyler and I finished the project and each did the same amount of work. What fraction of the project did I complete?
15

110

12

14

Answer 1

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
