In a company, 80% of the workers are women. if 880 men work for the company, how many workers are there in all?

If 80% are women, then 20% are men

20% of what equals 880

0.20x = 880

x = 880/.20

x = 4400

check ...

men : 20% of 4400 = 0.20 (400) = 880

women : 80% of 4400 = 0.80 (4400) = 3520

totaling : 3520 + 880 = 4400

so there are a total of 4400 workers
