david worked 7 1/3 hours today and planted 11 trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree? It took him _____hour to plant each tree.
0.66 or 0.7 (rounding)
To determine how long it took David to plant each tree, we can divide the total number of hours he worked by the number of trees he planted.
David worked for 7 1/3 hours, which can be expressed as 7 + 1/3 hours. To add the whole number and fraction, we need to convert the fraction into a common denominator. The denominator for the fraction is 3, so we rewrite 7 as 7/1 and add 1/3 to it:
7/1 + 1/3 = (7 * 3 + 1) / 3 = 22/3
Thus, David worked for a total of 22/3 hours.
Now, to find how long it took him to plant each tree, we divide the total time worked by the number of trees planted:
(22/3 hours) / 11 trees
To divide a whole number by a fraction, we multiply the whole number by the reciprocal of the fraction. In this case, 11 is the whole number, and 3/22 is the reciprocal of 22/3:
(22/3 hours) * (3/22 trees)
= (22 * 3) / (3 * 22) (hours cancel out, leaving only the trees)
= 66/66
= 1
Therefore, it took David 1 hour to plant each tree.
whats the answer??!!
7.33 / 11 = ________ an hour
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.
