Answer 1

Answer:

$let \: the \: number \: of \: girls \: be \: x$

$then \: number \: of \: boys \: = \frac{2}{5} \times \: x = \frac{2x}{5}$

$According \: to \: the \: problem</p><p>$

$x + \frac{2x}{5} = 56$

$\frac{5\times \: x + 2x}{5} = 56$

$\frac{5x + 2x}{5} = 56$

$\frac{7x}{5} = 56$

$7x = 56 \times 5$

$7x = 280$

$x = \frac{280}{7}$

$x = 40$

$therefore$

$number \: of \: girls \: = x = 40$

$number \: of \: boys = \frac{2x}{5} = \frac{2 \times 40}{5}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{80}{5} = 16$

$ther \: fore$

$\huge{no \: of \: girls \: = 40}$

$\huge{no \: of \: boys \: = 16}$
