    198.46 times. Take (1.908*10^24)/(6*10^21)=198.46

    If you need scientific notation, it's 1.9846*10^2

    Thank you, however how did you get 1.9846 I thought you multiply 6 x 1.908 to get 11.448

    Division is a ratio. Divide the mass of Jipiter by the mass of Earth.

    so it would be (1.908 x10^24) / (6 x 10^21)

    Check your math. The rule of exponents will allow us to subtract 10^24-10^21.

    ok then I have .318 x 10^3 right

    Nope, that would be 318.

    (1.908/6)=.198

    Before subtracting the exponents, simplify the rest of the fraction first.

    I understand the divide the mass of Jupiter by the mass of Earth. (1.908/6) but I get 0.318. I just don't get it. I ams sorry. But thank you very much for trying to explain it to me.
