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!
