Question

in a magazine 3/7 of the pages have advertisements on them even than 12 pages have advertisements on them , work out the number of pages in the magazine

Answer 1

If 3/7 of the magazine’s pages is 12 pages, then 1/7 of the magazine is 12/3=4 pages, and the whole magazine has 7 times this number of pages, so the magazine has 7×4=28 pages.
