5/10 divide each number by 5, 5 divided by 5 is 1 and 10 divided by 5 is two so it would be 1/2
4/12 divide each number by 4, four divided by 4 is 1, and 12 divided by 4 is 3 so it would be 1/3
3/9 divide each number by 3, 3 divided by 3 is 1, and 9 divided by 3 is 3 or it would also be 1/3
Hope that helped you
Answer: the sprinkling rate of the butler family's sprinkler is 40L per hour
the sprinkling rate of the Clark family's sprinkler is 20L per hour
Step-by-step explanation:
Let x represent the sprinkling rate of the butler family's sprinkler.
Let y represent the sprinkling rate of the Clark family's sprinkler.
The butler family's sprinklers was used for 40 hours. The Clark family's sprinkler was used for 30 hours. There was a combined total output of 2200L of water. This means that
40x + 30y = 2200 - - - - - - - - - - -1
if the sum of the two rates was 60l per hour, it means that
x + y = 60
Substituting x = 60 - y into equation 1, it becomes
40(60 - y) + 30y = 2200
2400 - 40y + 30y = 2200
- 40y + 30y = 2200 - 2400
- 10y = - 200
y = - 200/ - 10
y = 20
Substituting y = 20 into x = 60 - y, it becomes
x = 60 - 20 = 40
