Of the 216 students on the playground three-eighths are wearing white shoes how many children on the playground are not wearing
natka813 [3]
If 3/8 ARE wearing white schoes
Then 5/8 AREN'T wearing white shoes 
because

8/8 - 3/8 = 5/8
8/8 is the same as 1

Therefore, 
5/8 x 216/1 = y
If this is mental maths then,

You can cancel the 216 by 8 because the denominator of 5/8 is 8 to make 27

Therefore, the answer is 135
