Question

Half of a herd deer is grazing in the field and three fourths of the remaining is playing nearby. The rest 9 are drinking water from the pond. find the number of deers in the herd. ​

Answer 1

Answer:

72

Step-by-step explanation:

X/2= GRAZING

X/2 LEFT OF TOTAL

SO 3/4 OF X/2 = 3X/8 IS PLAYING NEARBY.

SO LEFT = X-(X/2+3X/8)

=X-7X/8

=X/8=9

SO X=72...

THEREFORE TOTAL NO. OF DEERS IS 72...

Answer 2

Answer:

mark me as brainliest

Step-by-step explanation:

let no. Of deer be x

No. Of deer grazing in the field = 1/2 into x = x/2

no. Of deer playing in the field = 3/4 into x/2 = 3x/8

deer drinking water from pond =9

so, x/2 plus 3x/8 plus 9

$4x + 3x + 9 \div 8 = x \\ 7x \div 8 = 9x \\ 8 = 9x - 7x \\ 8 = 2x \\ x = 8 \div 2 \\ x = 4$

so no. Of deer= 4
