The result is less than the whole number and greater than or equal to the decimal.
Unless the whole number is negative in which case the result is greater than the whole number and less than or equal to the decimal.
For the same reason that you can multiply two proper fractions and get a smaller number than either of them. You are multiplying either decimal by a number that is smaller than 1. As a result you get an answer that is smaller than 1 times the first number.
Nothing special happens. The answer can be smaller or bigger. A rational can become irrational or the other way around.
A decimal number, multiplied by 100, is its percentage.

Neither. A for every decimal number (which may itself be a whole number), there is a smaller whole number and for every whole number there is a smaller decimal number.
That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.

When there is only one number after the decimal point
To calculate 2.54 multiplied by 5, you simply multiply the two numbers together. 2.54 multiplied by 5 equals 12.7. This is because when you multiply a decimal number by a whole number, you multiply the decimal number by the whole number and then adjust the decimal point in the result accordingly.

There will be five decimal places.
Neither. A for every decimal number (which may itself be a whole number), there is a smaller whole number and for every whole number there is a smaller decimal number.
They also get smaller.
