Now,
![\text{Registered voters who participated}=(3)/(5)* 25](https://img.qammunity.org/2021/formulas/mathematics/high-school/q6aoptfu6ht96xxj5ulbl4yswrzr4unif8.png)
![\text{Registered voters who participated}=3* 5](https://img.qammunity.org/2021/formulas/mathematics/high-school/9755tij38hvmmemy1muwzdharvkeldwfwj.png)
![\text{Registered voters who participated}=15](https://img.qammunity.org/2021/formulas/mathematics/high-school/5su8psgisn3asf7wvv62wwijgyo2daz0b1.png)
