Answer:

The number of children living in Livingston is #900# and the total number of people living in Livingston is #4,800#.

Explanation:

The ratio of women to children is #7:3#. Since the number of women is #2,100#, the number of children #(x)# will be:

#x=2100xx3/7#

#x=300cancel2100xx3/(1cancel7)#

#x=300xx3#

#x=900#

The ratio of men to women is #6:7#. Since the number of women is #2,100#, the number of men #(y)# will be:

#y=2100xx6/7#

#y=300cancel2100xx6/(1cancel7)#

#y=300xx6#

#y=1800#

The total number of people is #1,800+2,100+900=4,800#.
