The mayor of renee's town chose 160 students from her school to attend a city debate. this amount is no more than 1/4 of the students in renee's school. what is the greatest number of students that attend renee's school?

a: 40
b: 160
c: 320
d: 640

The answer is d.
First you have to divide 160/ 1/4. So you would do 160/1 divided by 1/4. Because of keep, change and flip. (k.c.f) you would keep 160/1, change the division sign, then flip 1/4 to 4/1. Then you multiply 160/1*4/1. Then you would get 640. Hope this helped.
