Answers

  1. Answer:
    384
    Step-by-step explanation:
    480 students altogether.
    1/5 x 480 wear glasses
    1/5 x 480 = 96
    There are 2 ways to find out how many students do not wear glasses, each resulting in the same answer.
    Way 1:
    5/5 – 1/5 = 4/5 = do not wear glasses
    480 – 96 = 384
    Way 2:
    1/5 x 480 = 96
    5/5 – 1/5 = 4/5
    We need to find 4/5
    (1/5 x 480) x 4 = 4/5 x 480
    96 x 4 = 384
    Hope this helps!
