Question

The ratio of men to women in a certain factory is 3 to 4. There are 210 men.
Q: How many workers are there?

- Show your work.

Answer 1

There are 490 workers

3/4 = 210/x
Cross multiply, 210x4 and 3x
You're then left with 3x = 840, divide both sides by 3
This answer is 280 and represents the amount of female workers

Then just add 210 and 280, your answer is 490. Hope that helps!
