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.
What else can I help you with?
Are reciprocal fractions always a whole number?
No. The reciprocal of 2/3 is 3/2.
What do fractions help with?
Fractions help with numbers that are not whole numbers.
How is dividing integers similar to and different from dividing whole numbers?
Dividing integers and whole numbers both involve determining how many times one number fits into another, but they differ in their outcome and treatment of signs. When dividing whole numbers, the result is always a non-negative quotient or zero, while dividing integers can yield negative quotients depending on the signs of the numbers involved. Additionally, dividing whole numbers cannot result in fractions or remainders in the same way that integer division can, as integer division may involve negative results or remainders when dividing positive and negative integers.
How do you convert mixed fractions into whole numbers?

Are fractions whole numbers?
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).

How do you construct a pie chart?
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.
