this is a proportion question
20 cages= 4 hours
1 hours = 20/4 cages = 5 cages
10 hrs = 10*5 = 50 cages

First, you dive 20 by 4 to find out how many cages can be cleaned per hour. you should come up with 5. The, multiply those 5 cages per hour by 10, because there are 10 hours., giving you 50 cages in 10 hours.

The answer is 50 cages.
Set up a proportion:
20hrs/4 cages= x hrs/10 cages
Then, you cross multiply : 20 x 10= 200
Then divide 200/4= 50 (you solve for x)

No.
If he cleans 20 cages in 4 hours, that means he cleans 5 cages per hour.
That means if he works 10 hours he will clean 50 cages.

i got 50
well if he cleans 20 in 4 hours. 20 % 4 = 5
so he cleans 5 in 1 hr
5 x 10 = 50
