6. Find the fraction of work done by a person

Krishna's professor gave his a project to be completed by Sunday. He finished \((6 / 30)\) part of his work by Friday and \((14 / 30)\) part of his work by Saturday. What fraction of work he has to finish by Sunday to complete the project?

 

Krishna has to do $\frac{i}{i}$ of the work to complete the project.
