Question

Which one is the answer??

Answer 1

Answer:

B

Step-by-step explanation:

City X = 3 * 10^5            Given

City Y = 6 * 10^6

Times larger

6 * 10^6

3 * 10^5

Do the division

6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5)   Note 10^5 will cancel

60/3 = 20 City y is 20 times City x

Population Difference

6,000,000

   300,000

5,700,000

Just from the numbers I've given you, A is incorrect. The answer is 20 not 2.

B is the answer

C is wrong. X is 5.7 million less.
