Question

Neptune is about 2,700,000,000 miles from earth mercury is about 135,000,000 miles from earth determine how many times farther it is from earth to Neptune

Answer 1

2 or 2 x 10⁰

Explanation:

Answer 2

20 times further

Explanation:

Neptune is about 2,700,000,000 miles from Earth.

Mercury is about 135,000,000 miles from Earth.

Write in scientific notation to help solve. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The power is the number of decimal places you move.

2,700,000,000 = 2.7 x
`10^(9)`

135,000,000 = 1.35 x
`10^(8)`

2)

`(Neptune)/(Mercury) = (2.7 * 10^(9) )/(1.35*10^(8) )`

You can see there is only one extra 0 on top, the rest will cancel so you're left with:

`(27)/(1.35) = 20`

It's 20x farther to Neptune from Earth, than it is to Mercury from Earth.
