I need someone to tell me the answer to this and how to solve it
One day in the fall, Mark raked the leaves on 5 neighbors’ lawns in 2.5 hr. One day in the summer, he mowed 6 neighbors’ lawns in 1.2 hr.

The daily rate Mark rakes lawns in the fall is what percent of the daily rate he mows lawns in the summer, assuming he works at a constant rate.
