    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
