there are between 24 and 40 students in a class the ratio of boys to girls is 4:7 how many students are ther in a class

33 students

Step-by-step explanation:

4+7 = 11

No of students has to be a multiple of 11.

Between 24 and 40, the only multiple of 11 is 33

There are 12 boys and 21 girls for a total of 33 students

Explanation:

Since there aren't going to be fractions of people we can just count up using the whole numbers in the ratio and then check if the sum is between 24 and 40.

4:7→4+7=11<24 not enough

8:14→8+14=22<24 not enough

12:21→12+21=33

24<33<40 in the correct range!

There are 12 boys and 21 girls for a total of 33 students
