One-fifth of the students on the bus are wearing glasses. If there are 30 total students on the bus, how many are wearing glasses?

There are 30 total students.

1/5 of the 30 total students have glasses on.
Therefore, 1/5*30=6
That means there are 6 students on the bus that are wearing glasses.

So... to get 6 you basically just have to multiply 0.2*30??
