The Lawn Order lawnmower factory can produce 12 lawnmowers in 4 hours. How many hours will it take the factory to produce 63 lawnmowers?
A] 9 hours
B] 7 hours
C] 12 hours
D] 21 hours
4 / 12 = x / 63
4 / 63 = 12 * x
252 / 12 = x
21 = x
21 hours
Am I wrong?
You're right. D is the correct answer.
To find out how many hours it will take the Lawn Order lawnmower factory to produce 63 lawnmowers, we can set up a proportion.
We know that the factory can produce 12 lawnmowers in 4 hours.
Let's set up the proportion:
12 lawnmowers / 4 hours = 63 lawnmowers / x hours
To solve for x (the unknown number of hours), we can cross-multiply:
12 * x = 4 * 63
12x = 252
Now, we can solve for x by dividing both sides of the equation by 12:
x = 252 / 12
x = 21
Therefore, it will take the factory 21 hours to produce 63 lawnmowers.
The correct answer is option D] 21 hours.
