Question

The mass of Earth is about 6 X 1024

kilograms. The mass of the moon is about 7.4 X 1022
kilograms. About how many times greater is Earth's mass
than the mass of the moon?

Answer 1

81

Explanation:

To do "how many times greater" problems, you divide. Think how you would answer this: How many times greater is 48 than 6? Dividing the larger 48 by the smaller 6 gives 8. 48 is 8 times greater than 6.

Do the same thing for these two masses.

6 x 10^24 divided by 7.4 x 10^22 is about 81.
