The mass of Earth is about 6 X 1024
storchak [24]

Answer:

81

Step-by-step 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.
