Anwser = Factory B has 290 workers. Because it says that Factory A has 4 times as many workers as Factory B you will have to do 4 times the amount of workers Factory B has and you will get 1,160 which is how much Factory A has .To do that you have to do the opposite which is dividing by 4 and 4÷1,160=290 which is the amount of workers that Factory B has.
