Respuesta :

We will use the ratio method to solve this question

Class: Lefthanded

60 : 4

x. : 6

By using the cross multiplication

[tex]\begin{gathered} x\times4=60\times6 \\ 4x=360 \end{gathered}[/tex]

Divide both sides by 4 to find x

[tex]\begin{gathered} \frac{4x}{4}=\frac{360}{4} \\ x=90 \end{gathered}[/tex]

x represents the number of the students in the class

The class has 90 students
