2/3

To find out how long it took David to plant each tree, we need to divide the total number of hours he worked by the number of trees he planted.

First, let's convert the mixed fraction of 7 1/3 into an improper fraction.

7 1/3 = 7 + 1/3 = 21/3 + 1/3 = 22/3

Next, we divide the total number of hours by the number of trees planted:

22/3 hours ÷ 11 trees = (22/3) ÷ 11 = 22/3 × 1/11 = (22 × 1) ÷ (3 × 11) = 22/33

So, it took David approximately 22/33 hours to plant each tree.

If we simplify the fraction 22/33, we can get the answer in a different form:

22/33 = (2 × 11) ÷ (3 × 11) = 2/3

Therefore, it took David approximately 2/3 of an hour (or 40 minutes) to plant each tree.
