A group of 27 students in sixth grade rode their bicycles to school one day. This number represents 20% of sixth grade students at the school. What is the total number of students in sixth grade at this school?
One fifth of the students ride their bike to school. To get to one, multiply by 5. 1/5x5=1. Then, multiply 27 by 5. 27x5=135. There are a total of 135 students in sixth grade at this school. Hope this helps! ;)
