Answer from: cr22estiles

It takes him 2\frac{2}{3} hours to mow the third lawn

Explanation:

We are given that Evan takes 2\frac{1}{3} hours to mow Mr. Gals lawn and 1\frac{3}{4} hours to mow Mrs. Lee's lawn

This means that:

Time taken to mow the two lawns = 2\frac{1}{3} + 1\frac{3}{4} = 4\frac{1}{12} hours

Now, we are given that the time taken to mow the three lawns is 6\frac{3}{4} hours

This means that:

Time taken to mow the third lawn = 6\frac{3}{4} - 4\frac{1}{12} = 2\frac{2}{3} hours

Hope this helps :)
