# Maths Question.

Stuck on the last question, lol.

The mean density of the Earth is about 5.52, while that of the Moon is only 3.34.

A) if the Earth had the same volume as the Moon, how many times more massive than the Moon would it be?

Regards.

This comment I have entered did not contain enough characters - does now!!!

this is my kinda thinking but you woudl need to make that of the mass of the moon 1

somebody explain this to me im soo clujed

1.65X more massive?

No because the question is how much more massive is the Earth than the Moon, so the answer is the Earth is (5.52/3.34) times the mass of the moon and so is 5.52/3.34 more massive.

no self respecting ratio would look like that it would be *a figure*:1

such as a map 250,000:1

And not all ratio's are *a figure*:1, 2:3 is a ratio. Even 4:2 is a ratio but simplified it is 2:1 it doesn't however make it any less of a ratio.

Edited by:"bigfoot100" 26th Jan 2011id say your answer is 1.65 as previous concluded...

its a fair point but i think if you just gave an answer of 5.52:3.34 your teacher would be ****

im a little annoyed this question confused me at first but im a stickler for wording

I agree but I was trying to help the op get to the answer themselves rather than just giving them it.

Your obviously from a different planet to the rest of us (_;)

fair play, must admit i got a little lost in your first comment, thought it was gna be a lot harder question than it actually was and was confused by the format desired final figure
