Hi I am having a hard time figuring this out. There are 21 students in the class. 1 made a grade of 100, 2 made grades of 90 , 3 made 80, I know 11 students made below a 70. Please help me find the percentage, Dee |
Hi Dee,
Three students received a grade of 90 or more. The proportion of students who scored 90 or more was
3/21 = 0.1429. If you wish to express this as a percentage multiply by 100 to get 14.29%.
I hope this helps,
Penny
