schepotkina [342]

Given:

In an office, there are 75 women and 125 men.

To find:

The ratio of the number of men to the number of women.

Solution:

We have,

Number of men = 125

Number of women = 75

The ratio of the number of men to the number of women is:

\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}

\text{Required Ratio}=\dfrac{125}{75}

\text{Required Ratio}=\dfrac{5}{3}

\text{Required Ratio}=5:3

Therefore, the ratio of the number of men to the number of women is 5:3.
