Question

Nina completed a third of her homework problems. But one-half of all the problems she solved had incorrect answers. If 7 of the problems she solved had correct answers, then how many problems are in her homework?

Answer 1

`7 * 2 = 14`

Answer 2

so what you would do is you do it backwards, 7x2 which is one half of her problems do that I'd solved and you get 14. now you times that by 3 and you get the final answer 14x3
