Bill is in a class of 15 boys and 35 girls. 40% of the students in class take the bus to school. How many students did not take the bus to school?

20 kids

60% don't take the bus

Step-by-step explanation:

We know the % = a number / 100.

We know the % of students that take the bus is = 40%

what we don't know is (X) that represents the remaining percentage. so let set up the problem like this.

(X) + 40=100

X=100-40

X=60
