Last week Shane worked 45 hours. This week he worked 50 hours. Find the ratio of the increase in hours to the previous week of hours.

the ratio of increase is 1.11 or 11%.

Step-by-step explanation:

To find the increment ratio, we must divide the value of the hours of the current week by the value of the hours of the previous week.

R = Current week / Previous week

replacing

R = 50/45

R = 1.11

In other words, the ratio of increase is 1.11 or 11%.
