Answer: 
Step-by-step explanation:
10 pens - 2 pens = 8 pens
Write 8 of 10 as a fraction.
You get 
, right?
Now, simplify 8/10.
You get 4/5.
3 men
4 women
7 total
3 men/ 7 total = 198 men/ x total
using cross products
3*x = 7 * 198
divide each side by 3
x = 7*198/3
x = 462
There are 462 workers
If you mean 3 men and 1 women for a total of 4 workers when you state a ratio of men and women in a certain factory is 3 to 4.
3/4 =198/x
Using cross products
3x = 4* 198
Divide each side by 3
3x/3 = 4*198/3
x =264
264 workers
It all depends on how you define ratio of men and women in a certain factory is 3 to 4. This is incorrect phrasing and I took it to be men to women. You cannot have a ratio of men and women.
3x+3x+3x+y+3*2 ?
I only seperated the variabled number
