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?

 

I really need help with this plz help!!

7 correct and 7 incorrect = 14 problems so far        and this is equal to 1/3 of her homework

3 * 14 = 42 problems in all
