Take each digit in the number, and multiply it by the base in which expressed to the power of the column it's in. Note that the columns, going from right to left, use powers starting at zero and going up by one.
For example, look at any decimal number. Let's try 1976:
1976 = 1000 + 900 + 70 + 6 = 1×103 + 9×102 + 7×101 + 6×100
All bases work the same way, so converting to decimal can be done quite easily. For example, let's take the base 7 number "6143":
6143(7) = 6×73 + 1×72 + 4×71 + 3×70
= 6 × 343 + 1 × 49 + 4 × 7 + 3 × 1
= 2058 + 49 + 28 + 3
= 2138
so "6143" in base 7 is equal to "2138" in decimal.

As compared to converting decimal into what other base! It is no more difficult to convert decimal into base 8 than decimal into binary or Hex.
If it's anything other than the digits "1 9", then in order to convert it into a different base, we'd have to know what base it's in now.
The Sumerian system used base 60 whereas we now use base 10 (the decimal system).
There is only one Roman numeral for every number. Any other combination than LXXVI is incorrect and improper.
You can for the numeral IIII representing 4 but even that is normally written as IV, other than that generally no. 40 = XL, 400 = CD and 4000 = (IV)

It is 986, exactly in the question. If the number in the question was in some base other than 10, then I cannot guess what base it is meant to be in. In any case, if I were to guess, then I may as well make up my own questions and answer them!

Yes. Even so, that the Mayan numeral system was much more complex than the decimal system we use now: Maya numerals were a vigesimal (base twenty) numeral system.
There is only one Roman numeral for every number. Any other combination than LXXVI is incorrect and improper.
A non-numeral is any word or symbol that represents a numeral, but is not a numeral. Therefore, an example of a non-numeral less than ten is three.
You can for the numeral IIII representing 4 but even that is normally written as IV, other than that generally no. 40 = XL, 400 = CD and 4000 = (IV)
The Roman numeral that is greater than or equal to "C" is "D".
Convert both fractions to a common base and compare the size of their numerators.
Generally, it's easier to convert a fraction to a decimal than the reverse, but either way, convert one to the other and compare them.
This is because the base can neutralize the acid faster than a base
