Question

PLEASE HELP!!
Describe the relationship between number 7 x 109 and 1.4 x 1012.

Answer 1

answer is C 1.4 x 1012 is 200 times more than 7 x 109 :-}

Answer 2

We are given numbers
`7 * 10^9 \ and \ 1.4 * 10^(12).`

We need to describe the relationship between above given numbers.

Let us divide second number by first number.

`1.4 * 10^(12)` ÷
`7 * 10^9`.

On dividing 1.4 by 7, we get 0.2.

And on dividing
`10^(12) \ by\ 10^9`, we get
`10^(12-9) = 10^3`

Therefore,

`1.4 * 10^(12)` ÷
`7 * 10^9 =0.2 * 10^3` .

`0.2 * 10^3 =200.`

Therefore,
`1.4 * 10^(12)` is 200 times of
`7 * 10^9`.
