The lawn order lawnmower factory can produce 12 lawnmowers in 8 hours. How many hours will it take the factory to produce 30 lawnmowers?

If the factory can produce 12 lawnmowers in 8 hours, it can produce 1 lawnmower in 8/12 = <<8/12=0.6667>>0.6667 hours.

To produce 30 lawnmowers, it will take 30*0.6667 = <<30*0.6667=20.001>>20.001 hours.
Since we cannot have 0.001 hours, the factory will take 20 hours to produce 30 lawnmowers. Answer: \boxed{20}.

To find out how many hours it will take the factory to produce 30 lawnmowers, we can set up a proportion.

If the factory can produce 12 lawnmowers in 8 hours, we can write the proportion:

12 lawnmowers / 8 hours = 30 lawnmowers / x hours

To solve for x, we can cross-multiply:

12 lawnmowers * x hours = 30 lawnmowers * 8 hours

12x = 240

To isolate x, we can divide both sides of the equation by 12:

x = 240 / 12

x = 20

Therefore, it will take the factory 20 hours to produce 30 lawnmowers.

To find out how many hours it will take for the factory to produce 30 lawnmowers, we can use a proportion to set up an equation.

The proportion would be:
12 lawnmowers / 8 hours = 30 lawnmowers / x hours

To solve for x, we can cross-multiply and solve for x.

12 * x = 30 * 8

Now we can simplify the equation.

12x = 240

Dividing both sides of the equation by 12, we get:

x = 240 / 12

Simplifying further, we find:

x = 20

Therefore, it will take the factory 20 hours to produce 30 lawnmowers.
