Question

Clark wants to figure how many pens to order for the office. There are 48 workers, and he needs to order one pen for each worker. He knows that for every 3 people who prefer red, there are 9 who prefer blue.

Answer 1

12 red and 36 blue pens. 12/36 = 3/9 so the ratio is correct, and 12+36 = 48 workers.
