3/5 of Jill's 30 page photo album is full. She wanted to set aside 1/4 of the pages that are in there for vacation. How many pages can she fill before her vacation?

4 and a half to fill 30 in total minus the ones already used 30 - 18 = 12 A forth of the pages she wants to save which is about 7.5 of the total 12 - 7.5 Means she only has 4.5 pages left to use before she starts using her extra vacation pages
