7 ads for 3 pages, x ads for 150 pages. If you set it up as a proprtion, it is easy to solve. It's better to make your ratios look like fractions, with numbers properly over and under each other, instead of with the / between them. I can't do that here, but when you write it on paper, you can. 7a/3p = xa/150p cross multiply to get: 7a*150p = xa*3p 1050ap = 3xap divide both sides by 3ap to get 350 = x
