To move the decimal you must move the decimal in the divisor all the way to the right to make it a whole number. Then in the dividend, you move that decimal to the right the same amount of spaces you did in the divisor.

It is 10 millimetres, exactly as in the question. A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point.If you wanted 10 millimetres expressed as a [decimal] fraction of some other measure then you need to specify which.
Left.
If you have a fraction, divide the top by the bottom to get the decimal. If you have a decimal, move the decimal point 2 places that way --> to get the percent. If you have percent, move the decimal point 2 places this way <-- to get the decimal.
I assume you are talking about which way the decimal place would go. There are 10 millimetres in a centimetre. I.e. a millimetre is smaller than a centimetre. So when you're talking about decimal places, it would move to the left. This is because you need to divide.
If you have a decimal, move the decimal point two places that way ---> to get percent.
A decimal is a way of representing numbers, it has no measure itself. So 413 km, in decimal is exactly 413 km!

One kilometer = 1000 meters. To write it another way, 1.000 km = 1000 m Notice that all you had to do here was move the decimal point 3 places. So 1931.21 meters = 1.93121 kilometers.
Left or right - depending on what you are trying to do.
