Answer:

There are 42 women workers in the said factory.

Explanation:

Since 2/5 of the population in the said factory are men, therefore we need to find the remaining number of women workers there, which is in 3/5. (5/5 - 2/5 = 3/5)

In order to know the number of the whole population, we nedd to divide the number of men workers to its fractions as based on your question. (28 ÷ 2/5 = 70)

After that, subtract the number of men from the answer we got from our previous solution. In this way, we can get the number of women workers in the said factory. (70 - 28 = 42)

Conclusion:

There are 42 women workers wbo worked in the said factory.
