*24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

25 students

6 girls

Step-by-step explanation:

The problem can be solved by calculating the greatest common factor (GCF) between 24 and 30 (since it is 24% and less than 30 students).

For 24:

1x24

2x12

3x8

4x6

Factors of 24 = 1,2,3,4,6,8,12,24

For 30:

1x30

2x15

3x10

5x6

Factors of 30 = 1,2,3,5,6,10,15,30

GCF = 6

Then, we can conclude that 30/6 is the fraction of reduction which must be subtracted from 30, so to know how many students there are we apply the following formula:

30 - 30/6 = 30 - 5 = 25

The number of girls is calculated as follows:

25 x 24% = 25 x 0.24 = 6

In summary, there are 25 students, of which 6 are girls

Hope this helps!
