Question

You need about 1 ½ hours to set up a computer workstation. At this rate, how many hours should it take you to set up 7 of these workstations?

Answer 1

It should take 10 1/2 hours at this rate. If it takes 1 1/2 hours for one, setting up 7 means you just multiply by 7 (1.5 • 7 = 10.5).

Answer 2

10.5 hours—

1 1/2 = 1.5
1.5*7=10.5
