Find the ratio of number of students participated in English debate to the number of students participated in singing competition.

Answer 1

Given:

Total students$=36$

The number of students participated in a classical dance$=9$

The number of students participated in the English debate$=12$

$\Rightarrow$The number of students who participated in singing competition$=$$36-9-12$

$=15$

The ratio of the number of students participated in the English debate to the number of students participated in singing competition$=\frac{12}{15}$

$$\begin{gathered} =\frac{4}{5} \\ =4˸5 \end{gathered}$$

Hence, the ratio of the number of students participated in the English debate to the number of students participated in singing competition is $4˸5.$
