Answer:

  • There are 21 girls and 12 boys in the class. The class has a total of 33 students.

Explanation:

Let's add the ratios.

  • => 4 + 7 = 11

The only number that is divisible by 11 and is between 24 and 40 is 33. Let's divide 33 by 11.

  • => 33 ÷ 11 = 3

Now, let's multiply 3 to each ratio.

  • => 7 x 3 = 21
  • => 4 x 3 = 12

Hence, there are 21 girls and 12 boys in the class. The class has a total of 33 students.

Answer:

33 Students

Explanation:

4:7 => 4+7 = 11 < 24 not enough

8:14 => 8+14 = 22 < 24 not enough

16:28 => 16+28 = 44 > 40 alot more

12:21 => 12+21 = 33

24 < 33 < 40
