the number of deer in the herd
Hint let the number if deer in the herd be x
Number of those who are grazing = x upon 2
Remaining = x upon 2
Number of those who are playing = (3/4× x/2 = 3x/8
X/2 +3x/8=9=x find x

Answer 1

Step-by-step explanation:

let x be the no. of deers

half of the heard=x/2

3/4 of remaining =3/4*x/2

remaining =9

x/2+3/4*x/2+9=x

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

LCM=8

(4x+3x+72)/8=x

(7x+72)=8x

72=8x-7x

72=x

There are 72 deers in the heard
