Jamal hiked on two trails. The first trail was 3 1/3 miles long, and the second trail was 1 3/5 times as long as the first trail

The answer is 6.6 repeating, so 6.6666...

So first I took 1 and 3/5 and put it into decimal form which gave us 1.6, then I did the same with 3 and 1/3 and got 3.3 repeating, and now I multiply these and get 5.33333 repeating, and now I add the 3 and 1/3rd to get 6.6666 repeating.
