Question

Mr.Wells tells his class of 24 that when they have compleyed the assignment they may play online math games.At the end of class, 40% of the class is playing online math games. Approximately how many students still need to complete their assignment.

Answer 1

14 Students.

Explanation:

40% of 24 is 9.6 (Which should be approximated to 10). 24 Students in total - Approximately 10 who have completed the assignment is 14 students who still need to complete the assignment.

Answer 2

14

Explanation:

Because 40% of the class is playing games, that means (100-40)% aren't playing, meaning that those 60% haven't finished the assignment.

We find 60% of the total 24 students, and that is .6 * 24 = 14.4

Because you can't have .4 people, the answer rounds (down ) to 14
