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 than it is from earth to mercury.
1) convert each distance to scientific notation.
2) set up a ratio of the two distances and divide.
neptune/mercury=

Hey!

--------------------------------------------------

~Turn 2,700,000,000 into scientific notation.

2,700,000,000 / 10 = 270,000,000

270,000,000 / 10 = 27,000,000

27,000,000 / 10 = 2,700,000

2,700,000 / 10 = 270,000

270,000 / 10 = 27,000

27,000 / 10 = 2,700

2,700 / 10 = 270

270 / 10 = 27

27 / 10 = 2.7

We divided 2,700,000,000 by 10 nine times to get 2.7

In scientific notation is 2.7 x 10⁹

--------------------------------------------------

~Turn 135,000,000 into scientific notation.

135,000,000 / 10 = 13,500,000

13,500,000 / 10 = 1,350,000

1,350,000 / 10 = 135,000

135,000 / 10 = 13,500

13,500 / 10 = 1,350

1,350 / 10 = 135

135 / 10 = 13.5

13.5 / 10 = 1.35

We divided 135,000,000 by 10 eight times to get 1.35

In scientific notation is 1.35 x 10⁸

--------------------------------------------------

Ratio:

Solution: 2,700,000,000 / 135,000,000 = 2

2 or 2 x 10⁰
