Well, for one thing, it is easier to multiply than to divide. If you divide by a fraction, the answer is the same as multiplying by its reciprocal. For example, how much is 100 divided by 1/2? If you say 50, that's wrong. That's 100 times 1/2. Suppose you have $100 and you want to buy as many candy bars as you can at 50 cents each. That's 1/2 a dollar. If you bought 100 candy bars, that would cost $50. You have twice that much money, so you could buy twice as many. You could buy 200. So 100 divided by 1/2 is 200, not 50. The reciprocal of 1/2 is 2, and 100 times 2 is 200.
No. The reciprocal of 2/3 is 3/2.
Fractions help with numbers that are not whole numbers.
Mixed fractions can't become whole numbers.
adding fractions is like adding a WHOLE lot of parts of numbers
The majority of fractions will not be able to become whole numbers. Certain improper fractions, where the numerator is a multiple of the denominator, can become whole numbers. No proper fractions can.
The reciprocal of any whole number is one over that number, like 5 and 1/5
No. The reciprocal of 2/3 is 3/2.
You simply put the whole number over one making it a fraction then you flip the reciprocal and divide the two fractions insted of multiplying.
When dividing by negative numbers or dividing by fractions.
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).

There are an infinite number of both fractions and whole numbers.
Ok, first you take whatever numbers you're using and put them into fractions of a whole. After that, turn the fractions into percentages by dividing. Next, make a circle and take the fractions and make them into parts of the whole circle. The measurements usually do not need to be perfect.
