To Find :

To find the percentage of boys and girls

______________________________________________

Number of boys in a class =20

Number of girls in a class =18

Total Class size =20+18=38

Ratio of boys vs girls =10:9

Now,finding percentage of boys and girls

$= \frac{20}{38} \times 100 = \frac{2000}{38} = 52.63{\&#37}$

Percentage of girls:$= \frac{No.of \: Girls}{total \: class \: size}$

$=\frac{18}{38} \times 100 = \frac{1800}{38} = 47.36{\&#37}$
