Q. Find the au.

\newline

In a class of

30

students, there are

14

boys. What is the boy-girl ratio in the class?

Find Girls Count: First, find out how many girls are in the class by subtracting the number of boys from the total number of students. $\newline$ Calculation: $30$ students - $14$ boys = $16$ girls.
Calculate Boy-Girl Ratio: Now, to get the boy-girl ratio, we compare the number of boys to the number of girls. $\newline$ Calculation: The ratio of boys to girls is $14$ boys : $16$ girls.
Simplify Ratio: We can simplify the ratio by dividing both numbers by the greatest common divisor, which is $2$ in this case. $\newline$ Calculation: $(14 \div 2) : (16 \div 2) = 7 : 8$ .
