Question

Convert $15$ years $3$ months into year.

Answer 1

we know that $\text{1 year = 12 months}$

So, to convert months to years, we need to divide months by $12.$

$$\begin{gathered} \text{15 years 3 months}=\left(15+\frac{3}{12}\right)\text{years} \\ =\left(15+\frac{3÷3}{12÷3}\right)\text{years} \\ =\left(15+\frac{1}{4}\right)\text{years} \\ =15\frac{1}{4}\text{years} \end{gathered}$$

Hence, $15$ years $3$ months in years is $15\frac{1}{4}$.
