INFORMATION:
We have the following options
100,000
10,000
1,000,000
1,000
And we must select the one that indicates how many times the prefix “mega-“ is larger than the unit it precedes
STEP BY STEP EXPLANATION:
To select the correct one, we need to know that the prefix “mega-“ belongs to prefixes of larger quantities and represents a factor of 10^6.
That means, the prefix “mega-“ is 10^6 times larger than the unit it precede.
Now, we can rewrite 10^6 as

Finally, we can state that the prefix “mega-“ is 1,000,000 times larger than the unit it precedes
ANSWER:
1,000,000
