A) 2 x 10^7 is 7 times larger than 4 x 10^6
B) 2 x 10^7 is 6 times larger than 4 x 10^6
C) 2 x 10^7 is 5 times larger than 4 x 10^6
D) 2 x 10^7 is 3 times larger than 4 x 10^6

Answer 1

Answer:

C. $2\times 10^7$ is 5 times larger than $4\times 10^6$

Step-by-step explanation:

We want to compare $4\times 10^6$ and $2\times 10^7$.

In order to determine how many times

$2\times 10^7$

is larger than

$4\times 10^6$,

we need to divide $2\times 10^7$ by  $4\times 10^6$ to obtain;

$\frac{2\times 10^7}{4\times 10^6} =\frac{10}{2} =5$

Therefore we can see that;

$2\times 10^7$ is 5 times larger than $4\times 10^6$

The correct answer is C.
