7.33 / 11 = ________ an hour
whats the answer??!!
0.66 or 0.7 (rounding)
7 1/3 divided by the number of trees (11).
1. Change 7 1/3 to an improper fraction. = 22/3
2. 22/3 divided by 11
3. Change 11 to a fraction by putting it over 1 = 11/1
4.Change the division problem to multiplication by leaving the first fraction, changing the division sign to multiplication, and flipping the last fraction.
Your problem will now look like the below:
22/3 x 1/11
5. Cross cancel if you can. In this case, 22 and 11 can be reduced. Your problem will now look like the below:
2/3 x 1/1
6. Multiply straight across and you get 2/3.
7. 2/3 of an hour is 40.
8. It took David 40 minutes to plant each tree.
