Question

Convert 15 months into years.

Answer 1

Hint: We first find the relation between months and years. The measurement is common in measurement units of time. We find the relation as 12 months being equal to 1 year. We use the unitary system to find the year value for 15 months.

Complete step by step solution:
We need to convert the unit of time by changing from months to year.
We find the relation between months and year as 12 months being equal to 1 year.
We already have that in the unitary system. The unitary method is a method in which we find the value of a unit and then the value of a required number of units. The unitary method is also used to find the value of a single unit from a given multiple.
We need the equivalent time of 15 months.
So, 1 month is equal to $ \dfrac{1}{12} $ year.
We multiply 15 with $ \dfrac{1}{12} $ to get the time length which will be equal to 15 months.
Therefore, 15 months is equal to $ 15\times \dfrac{1}{12}=\dfrac{15}{12}\text{=}1.25 $ years.
Therefore, 15 months is equivalent to $ \text{1}\text{.25} $ years.
So, the correct answer is “ $ \text{1}\text{.25} $ years”.

Note: The months and years are units of measurement for time in both the US customary units and the metric systems of measurement. This unit is used in the normal or common measurement units. It can also be changed to other common measurement units using the relation in the metric system.
