Answer:

If there are 22 boys out of 40 pupils, then there would be 18 girls.

Since 18 and 40 are both divisible by 2, we're going to divide them by 2.

Fraction:

  • [tex]\tt{\frac{18}{40}=\frac{18\div2}{20\div2}}=\boxed{\tt{\frac{9}{20}}}[/tex]

Ration:

  • [tex]\tt{18:40=18\div2:40\div2}=\boxed{\tt{9:20}}[/tex]
