It is not a requirement. However, it is easier to divide mentally if the denominator is a rational number.
No. Dividing by zero is undefined. It does not result in anything.
No difference. The set of complex numbers includes the set of imaginary numbers.
imaginary numbers are numbers that are a negative square root, which is not possoble therefor it is called and imaginary number. ex the square root of -24 is an imaginary number
This is because dividing by a number is the same as multiplying by its reciprocal.
By dividing both the numerator and denominator by the same number is like dividing by 1.
No.
Yes it is. All pure imaginary numbers (such as 5i) as well as all real numbers and any combination of real & imaginary (by adding, subtractin, multiplying, dividing) makes a complex number.

A mixed number can be converted into an improper fraction. Mixed numbers as improper fractions can be divided just like any other fraction. To convert a mixed number to an improper fraction multiply the whole number by the denominator and add the original numerator to give the new numerator and put this over the original denominator.

simplify by dividing
You make a mixed number by dividing the merator to the denominator by putting the remainder over the denominator.
Consider 23/1.344 This can be written as 23000/1344 (we multiplied both numerator and denominator by 1000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers. Consider 23.089/4.6788 This can be written as 230890/46788 (we multiplied both numerator and denominator by 10000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers.
