The stickers were 4 inches wide by 6 inches longs. The posters were proportional to the stickers, and they were 18 inches wide. How long were the posters? Answer: To solve this problem, set up a proportion: (poster length)/(poster width) = (sticker length) /(sticker width) (poster length)/(18) = (6) /(4) To solve for the poster length, multiply each side of the equation by 18 (poster length)/(18) = (6) /(4) [(poster length)/(18)]*18 = [(6)/(4) ]*18 (poster length)*(18/(18) = [(6)/(4) ]*18 (poster length)*(1) = [(6)/(4) ]*18 poster length = [(6)/(4) ]*18 poster length = 27 the final answer is: Poster Length = 27 inches Thanks for writing.
