Answer:
1:3
Step-by-step explanation:
We are given that
Total number of students in Mr Kole's class=30
Number of girls=Twice the number of boys.
We have to find the ratio of boys to total students.
Let number of boys in the class=x
Total number of girls in the class=2x
Total students in the class=30
[tex]x+2x=30[/tex]
[tex]3x=30[/tex]
[tex]x=\frac{30}{3}[/tex]
By using division property of equality
[tex]x=10[/tex]
Number of boys in the class=10
Ratio of boys to total students=[tex]\frac{10}{30}=\frac{1}{3}[/tex]
Ratio of boys to total students=1:3
