32-15 first you would have to subtract the 2 and the 5 but you will have to borrow from the three make the 3 a 2 and make the 2 a 20 then subtract 5 - 20 is 15 so carry the 1 to the 2 and bring down the 5 so now 1 - 2 is 1 + the 1 = 25 :)

Answer:</h3>
6 hours 36 minutes, or 6 hours 31 1/2 minutes
<h3>
Step-by-step explanation:</h3>
Dividing the task among the 6 committee members means each member will be making 525/6 = 87.5, that is, either 87 or 88 flowers. (We doubt that two people working together on the same flower will finish it in half the time.)
Each of the three committee members making 88 flowers will take ...
... 88 × 4 1/2 minutes = 396 minutes = 6 hours 36 minutes
Each member making 87 flowers will be finished 4 1/2 minutes sooner, after 6 hours 31 1/2 minutes.

<em>Comment on the problem</em>
This problem seemingly invites you to divide the labor evenly among committe members. Doing that would give you an answer of 6 hours 33 3/4 minutes. You need to ask yourself whether that is practical for this situation.
Given:
Total number of girls in her class = 16
Total number of boys in her class = 14
To find:
The number of different ways of choosing one girl and one boy.
Solution:
We have,
Total number of girls = 16
Total number of boys = 14
So,
Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
Now, number of different ways of choosing one girl and one boy is
Therefore, the required number of different ways is 224.
