It would be easier to translate this into mathematical terms first.
Let n = the unknown number
6n <span>> n + 20
Subtracting both sides by n to simplify:
6n - n </span><span>> n + 20 - n
</span>5n <span>> 20
</span><span>
Dividing both sides by 5:
5n/5 </span><span>> 20/5
</span>n <span>> 4
</span><span>
Among the choices, the correct one is the second choice.
</span>
Welp, looking at the number: 66
......
The second digit "6" is up to or more than 5.
...............
So, we can clearly round it up.
.....................
In this case, we are rounding to the nearest hundredth.
.............................
Hm, 100 is pretty close to 66.
..................................
We can now say that the nearest hundredth is 100.
...............................................
BAM! *drops mic*
