because humans have 10 fingers, in olden days they used to count using their fingers
Presumably because the digits on their hands add up to 10
It is mainly because humans have ten digits: fingers and thumbs. As a result, from prehistoric times, one of our counting bases has been ten.
There is no such example. If you cannot use an exact fraction then there will not be an exact decimal that you can use instead. And, if you are using an approximate decimal, you could use an approximate fraction instead.
terminating decimal is when the quotient has the remainder of zero.
To type a decimal point, you use the period key. .

Computers use a binary system, not decimal.

Yes, South Africa does use the decimal system
If the number is already in decimal form, you do not need to do anything to "convert" it to decimal!
how can you use expanded notation to find an equivalent decimal
You can never use more than one decimal point.
That will depend on the nature of the numbers. If there are no decimal places, you could use a right tab. If there are decimal places, you could use a decimal tab. If the numbers will all have the exact same amount of digits, then you could use a left, decimal or right tab.
