Question

Chai started to run on a treadmill after setting its timer for 62 minutes. The display says that he has finished 53% of his run. How many minutes have gone by? Round your answer to the nearest tenth.

Answer 1

About 32.9 minutes have gone by.

To find this answer you take your percent and make it a decimal by dividing it by 100. In doing so, you'll get 0.53. Then multiply 0.53 by 62 to get 32.86. Since you have to round to the nearest tenth, you look at the hundredths place to see whether you round up (5-9) or round down (1-4). In this case, you round up making your answer 32.9 minutes.

I hope this helps!
