    Answer:

    B

    Step-by-step explanation:

    Begin by answering this question: Which is bigger 10^5 or 10^3?

    10^5 = 100,000

    10^3 = 1000

    So the correct answer is going to found by comparing the 10^5 number to the 10^3 number.

    Jupiter: the Earth’s moon :: 1.4*10^5 : 3.5 * 10^3

    Jupiter / Earth’s moon = 1.4 * 10^5 / 3.5 * 10^3

    Jupiter/ Earth’s moon = 40/1

    That’s a surprising result that I didn’t know before.  I thought the difference would be much larger.

    As an add on can you do this on your calculator (using scientific notation)?

    If not you could do it like this

    Jupiter / earth’s moon = 140000 / 3500
