Question

During Christmas a book store sold 28 books. If the ratio of books to bookmarks sold was 7 : 3, how many bookmarks did the store sell?

Answer 1

if it is books to bookmarks and the ratio is 7:3 then u make the 7 into 28 like 28:x
to find out x u figure out how many times 7 goes into 28 so this time 4 so u multiply the 3 from the ratio to get 12 so it becomes 28:12

this means the shop sold 12 bookmarks
