Question

The populations of two towns, town A and town B, are being compared. The population of town A is 4×10^4 and the population of B is 2×10^5. How many times greater is the population of town B than town A?

Answer 1

Answer:

5 times

Step-by-step explanation:

Given that,

The population of town A is 4×10⁴

The population of town B is 2×10⁵

Let the population of town is B is x times of the town A. So,

$A\times x=B\\\\x=\dfrac{B}{A}\\\\x=\dfrac{2\times 10^5}{4\times 10^4}\\\\x=5$

It means that the population of town B is 5 times of the population of town  A.
