Question #11635

See explanantion

Explanation:

Let the count of boys be $b = 32$
Let the count of girls be $g = 40$

In fractional format the ratio is:

$\left(\text{girls")/("total}\right) \to \frac{g}{g + b} = \frac{32}{32 + 40} = \frac{32}{72}$

$= \frac{32 \div 2}{72 \div 2} = \frac{16 \div 2}{36 \div 2} = \frac{8 \div 2}{18 \div 2} = \frac{4}{9}$

In what I call clock form the ratio is

$\text{girls : total " = " } 4 : 9$
