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 $\left(x\right)$ will be:

$x = 2100 \times \frac{3}{7}$

$x = 300 \cancel{2100} \times \frac{3}{1 \cancel{7}}$

$x = 300 \times 3$

$x = 900$

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

$y = 2100 \times \frac{6}{7}$

$y = 300 \cancel{2100} \times \frac{6}{1 \cancel{7}}$

$y = 300 \times 6$

$y = 1800$

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