There are between 24 and 40 students in a class. The ratio of boys to girls is 4:7
How many students are in the class?

Step-by-step explanation:

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.

Let’s begin:

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

33

Step-by-step explanation:

Find the total units of students in the class.

4 + 7 = 11 units

Try dividing 11 with numbers from 24 to 40, if one of them gives a whole number, it is the answer.

Multiples of 11:

11, 22, 33, 44

So it's 33 as it is between 24 to 40.
