In a class of 28 students,:
Total number of students = 28
There are 13 boys.
Number of Boys = 13
So, Number of girls = Total number of students - number of boys
Number of girls = 28 - 13
Number of girls = 15
The ratio of boys to girls in the class is express as:
[tex]\begin{gathered} \text{ Ratio of boys to girls =}\frac{Number\text{ of boys}}{Number\text{ of girls}} \\ \text{ratio of boys to girls = }\frac{13}{15} \\ \text{ratio of boys to girls =13 : 15} \end{gathered}[/tex]Ratio of boys to girls = 13 : 15
Answer : Ratio of boys to girls = 13 : 15
