Answer:
"1,000 times greater"
Explanation:
We will do the calculation in BYTES.
We want to figure out HOW MANY TIMES GREATER is 1 Gigabyte than 1 Megabyte.
1 Gigabyte (GB) = 10^9 Bytes
1 Megabyte (MB) = 10^6 Bytes
So, how many times is 10^9 is of 10^6? We just need to divide 10^9 by 10^6.

So, 1 GB is 1000 times greater than 1 MB.
