Answer:
33 students.
Step-by-step explanation:
There are between 24 and 40 students in a class.
The ratio of boys to girls is 4:7.
4×3:7×3
12:21
12+21=33
33 students in the class, which is between 24 and 40 students in a class.
4×2:7×2
8:14
8+14=22
22 is wrong because it has to be between 24 and 40 students in a class.
4×4:7×4
16:28
16+28=44
44 is wrong because it has to be between 24 and 40 students in a class.
4×1:7×1
4:7
4+7=11
11 is wrong because it has to be between 24 and 40 students in a class.
