if a person spends 45 minutes getting to work and 45 minutes returning home, what percent of the day does the person spend commuting?

Question

similar to classwork question and have always had a difficult time with ratios.

Answer 1

The person in question spends 45 + 45 = 90 minute = 1.5 hrs commuting.

 

So the fraction of a day for commuting is 1.5/24 = 0.0625 = 0.0625 (100%) = 6.25%

 

I think the easiest way to get percentage is to just dividing the number with a calculator,

then multiply the result by 100. For this problem

 

0.0625 = 0.0625 (100%) = 6.25%

 

If you need to work with ratios, then try this

1.5/24

= 15/240  {Multiplying numerator and denominator by 10 to get rid of the decimal)

= 5/80    

= 1/16
