half of a herd of deer are grazing in the field and three fourths of the remaining are playing nearby.the rest 9are drinking water from the pond. find the number of deer in the herd
The answer is 24.I'll tell how:
x=The total number of deer in the herd.
Half of them are grazing in the field,so x/2=The number of deer grazing.
Let's call the result of x/2 "y".Now y*3/4 has to be=9,because 3/4 of y is the number of deer playing and the rest 9 are drinking.
To find the number for y,we have to use the opposite operation for multiplication,that is,division.
So,9 divided by 3/4 is 12,and that's "y".
Now that we know that y=12,to find x we simply multiply 12 by 2 since y=x/2
So,12*2=24 - Ans.
