Not too sure but I think you’ll have to find out the amount of boys in the class then add that number to the amount of girls to get the answer.
So 3:4::198:?. 3 is to 198 as 4 is to ?. You're solving for ? so you want that on the top of the fraction. 4/3=?/198. Multiply both sides by 198. ?=(4/3)(198)=264 women. Then add the men. 264+198=462 workers.
Check your work. (462/7)*3=198 men.
