1. ## Scientific Notation, Mass =URGENT=

How many times greater is the mass 1.2 x 10^27 than 6 x 10^24?
- Help Appreciated

Edit: Ahh, neverming; i worked it out accidentally...

2. 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
