answer question no. 8 plz thanks

Answer 1

there are 72 deer in total.

Answer 2

let there be x deers in total. so 1/2 of x are grazing. there fore another 1/2 of x are remaining. 3/4 of the remaining 1/2 x deers are playing. which means that 3/8 of x are playing. after that 9 are remaining
therefore
$x - \frac{1}{2} x - \frac{3}{8} x = 9 \\ \frac{8x - 4x - 3x}{8} = 9 \\ \frac{x}{8} = 9 \\ x = 72$
