City X has a population 4 times as great as the population of City V, which has a population twice as great as the population of City Z. What is the ratio of the population of City X to the population of City Z?

Answer: 8:1

Step-by-step explanation:

X = 4*

V = 2*

Z = 1x

Answer = Z*V*X

ratio of City X to City Z is 8:1

Step-by-step explanation:

City X has a population 4 times as great as the population of City V

x=4v

City V which has a population twice as great as the population of City Z

So v = 2z

Let City Z population is

then city V population is twice that is 2

City Y has a population twice as great as the population of City Z

Let's say the population of City Z is 1 person

This means the population of City Y is 2 people

City X has a population 4 times as great as the population of City V

so City X population is 4 times 2 = 8

so x=8 and Z=1

so ratio of City X to City Z is 8:1
