Answer 1

$\huge{\mathfrak{\red{\boxed{\green{\underbrace{\overbrace{\blue{†Answer†}}}}}}}}$

Let the number of deer be X

Number of deer grazing = 1/2ofx

= X/2

deers playing near by = 3/4ofx/2

= 3x/8

deer drinking water = 9

total deer =

X/2+3x/8+9 = X

X/2+3x/8+9/1 = X

Taking LCM

$\frac{4x + 3x + 72}{8} = x$

$4x + 3x + 72 = 8x$

$7x + 72 = 8x$

$8x - 7x = 72$

$x = 72$

Total number of deer in herd is 72

Hope it helps........
