At brown Elementary school, 80% of all fifth graders ride the bus to school. If 124 fifth graders ride the bus to school, how many fifth graders are there at the school.

Answer:155 5th graders
Step-by-step explanation:
1: Divide 124 by 80% so you know the amount of 5th graders per 1%
124/80=1.55
2: Multiply 1.55 by 100 to get the amount of 5th graders per 100%
(1.55)(100)=155
