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
Answer:
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.
