    ok now this is my approach

    a = 1.2 x 10^27
    b = 6 x 10^24

    equating them both

    A/B = 1.2/6 x 10^27/10^24

    A = 0.2 x 10^3B

    A= 200B

    therefore a is 200 times greater than B

    Correct.

    Hey, as long as you understand it, any which way is correct, so long as the answer is correct.

    Math is a language. Say it, interpret it the way you want.

    But if you want to go with the general population who speaks Math, you could have said it like this:
    A = 1.2 x 10^27 ----------(1)
    B = 6 x 10^24 --------------(2)

    Divide (1) by (2),

    A/B = (1.2 x 10^27) /(6 x 10^24)
    A/B = (1.2 /6) x (10^27 / 10^24)

    A = (0.2 x 10^3)B

    A= 200B

    therefore A is 200 times greater than B
