If of the telephone workers in a city are female, what percent are female?  $\frac { 2 } { 5 }$

Quizplus · Accepted Answer

To find the percentage of female telephone workers, we need to divide the number of female workers by the total number of workers and then multiply by 100 to get the percentage.

If we let the total number of telephone workers be represented by the variable x, and we know that 2/5 of them are female, we can set up the equation:

2/5 = (number of female workers) / x

To solve for the number of female workers, we can multiply both sides by x:

2/5 * x = number of female workers

Simplifying:

0.4x = number of female workers

To express this as a percentage, we divide the number of female workers by the total number of workers and multiply by 100:

(number of female workers) / x * 100 = percentage of female workers

Substituting 0.4x for "number of female workers", we get:

0.4x / x * 100 = percentage of female workers

Simplifying:

0.4 * 100 = percentage of female workers

Therefore, the percentage of female telephone workers is 40%, which corresponds to choice C.
