Question

In converting 105 seconds to minutes, what unit (omit the number) would you place in the denominator of your ratio? Use the plural form in your answer. Remember that there are 60 seconds in 1 minute.

Answer 1

Convert 105 seconds into minutes

60 seconds = 1 minute

105 seconds * 1minute/60 seconds = (105 * 1 minute)/ 60 = 105 min / 60 = 1.75 minutes

The unit that you place in the denominator of your ratio is seconds. This will cancel out the seconds placed in the numerator of 105.
