Answer:

384

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!
