Question

if there are 170 students in 12th grade what percentage of the total grade students have more than one college their mind

Answer 1

70%

Explanation:

Out of all the 12th grade students there are 27 who are looking at 2 colleges and 23 looking at 3+.

First you need to add the 27 looking at 2 colleges and the 23 looking at 3+.

27+23 = 50

Now you take the total 12th grade students (170) and subtract it by the total number of 12th grade students looking at 2 and 3+ colleges (50) and put that all over the total.

`(170-50)/(170)` ->
`(120)/(170)`

Then you solve which would be

0.70 or 70%
