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.
