Clark wants to figure out 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 six people who preferred , there are six who prefer blue . How many blue pens should he order?

the ratio is 6:6, making 12 total.
48 = 12*4, so 24:24 will satisfy everyone.
