Question

There are some books on a shelf and 12 are cookbooks. If 20% are cookbooks, how many books are on the shelf

Answer 1

If u take 12 divided by .20 you would get 60 because if u think of it as a dinner bill say it is $60.00 and I want to give a 10% tip it would be $6 but if u give a 20% tip u would give $12
