    Answer:

    Step-by-step explanation:

    If \frac{2}{3} passed the exam then:

    \frac{3}{3} -\frac{2}{3} = \frac{1}{3} failed the exam

    now to find the number which failed we multiply:

    \frac{1}{3} \cdot 120 = 40 and 40 is our answer

    Answer:

    40 failed

    Step-by-step explanation:

    2/3 of 120 is 80, so you subtract the 80 who passed from the 120 total to get 40 students who failed
