Part A.

We know there are 12 months in a year, then we have the following rule of three:


\begin{gathered} 1\text{ year ------- 12 months} \\ x\text{ ---------- 72 months} \end{gathered}

weere x denotes the corresponding years for 72 months and is given by


x=\frac{(1\text{ year)(72 months)}}{\text{12 months}}

that is,


\begin{gathered} x=(72)/(12)\text{years} \\ x=6\text{ years} \end{gathered}

Therefore, 72 months is equal to 6 years.

Part B.

In this case, we know there are 365 days in 1 year then our rule of three is


\begin{gathered} 365\text{ days ------ 1 year} \\ x\text{ ----------- 6 years} \\ so,\text{ we get} \\ x=\frac{(365\text{ days)( 6 years)}}{\text{1 year}} \\ x=365*6\text{ days} \\ x=2190\text{ days} \end{gathered}

this means that in 72 months (6 years) there are 2190 days.

Part C.

We know there are 24 hours in 1 day, so our rule of three is


\begin{gathered} 24\text{ hours ------ 1 day} \\ x\text{ ---------- 2190 days} \\ \text{then, x is given as} \end{gathered}
\begin{gathered} x=\frac{(24\text{ hours)(2190 days)}}{\text{1 day}} \\ x=\text{ 24}*2190\text{ hours} \\ x=52560\text{ hours} \end{gathered}

Hence, 72 months are equal to 52560 hours
