Gerri is working on a project that needs to be halfway completed by Friday. So far, she has completed 1/3 of the project. How much of the project does she have to finish by Friday?
So far Gerri is 1/3 complete and needs to be 1/2 complete by Friday. In order to find how much needs finished by Friday, we subtract the fractions. 1/2 - 1/3 1/2 + (-1/3) 3/6 + (-2/6) (3+(-2))/6 1/6 Hope this helps
