Question

Compare 4 x 10^6 and 2 x 10^7.

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

C.
`2* 10^7` is 5 times larger than
`4* 10^6`

Explanation:

We want to compare
`4* 10^6` and
`2* 10^7`.

In order to determine how many times

`2* 10^7`

is larger than

`4* 10^6`,

we need to divide
`2* 10^7` by
`4* 10^6` to obtain;

`(2* 10^7)/(4* 10^6) =(10)/(2) =5`

Therefore we can see that;

`2* 10^7` is 5 times larger than
`4* 10^6`

The correct answer is C.
