Scott made 216 for 18 hours of work how many hours to make 144

12 hours

Step-by-step explanation:

216           144

   =    

18               x

144 x 18 = 2,592

2,592 / 216 = 12

12 hours

Step-by-step explanation:

Make a proportion

He made 216 for 18 hours of work, and 144 for x hours of work

216/18=144/x

Cross multiply

216*x=18*144

216x=2592

We want to solve for x, and to do this, we need to get by itself. It is being multiplied by 216. To reverse this, do the opposite of multiplication: division.

Divide both sides by 216

216x/216=2592/216

x=12

He will need to work 12 hours
