Step-by-step explanation:

Let,

The number of boys be = x

So,

Number of the girls = 3 × x

= 3x

Therefore,

Ratio of number of girls to number of boys in school will be,

[tex] = \frac{number \: of \: girls \: in \: school}{number \: of \: boys \: in \: school} [/tex]

  • [Putting the number of boys and girls]

[tex] = \frac{3x}{x} [/tex]

  • [On cancelation of x]

[tex] = \frac{3}{1} [/tex]

  • [In ratio]

= 3:1 (Ans)
