Question

Rob and Nancy are working on a project. Rob completes 1/8 of it on Monday and 3/8 on Tuesday. Nancy completes 2/6 of it on Wednesday and 1/8 on Thursday. Is the project complete? Explain

Answer 1

just look at the summations:
rob:1/8+3/8=4/8=1/2 so he didn’t finish.
Nancy: 2/6+1/8=16/48+6/48=22/48=11/24 so she didn’t finish it,too.
