Sarah earned 80%on her science quiz. if there werea toatl of 15 questions worth onepoint a piece, how many questions dod she get right? How many more questions would she have needed to get an A?
×/80 = 15/100.. you would multiply the fractions as if you were doing division.. x × 100 = 80 × 15.... that comes to 100x = 1200... you divided 1200 by 100... that is 12... so she got 12 questions right and 3 wrong.. she would need 3 more to get an A
