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?

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

5 pm

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
