A teacher gave a test with 50 questions, each worth the same number of points. Donovan got 39 out of 50 questions right. Marci's score was 90%.
 

How many more questions did Marci answer correctly?
 

PLEAse help

Respuesta :

So Marci's sore was 45 because every percent has to be out of 100 so to get it to 50 you divide by two so 90 / 2 = 45. And 45-39 = 6 

Marci got 6 more correct then Donovan.
