Many people, even when they are naturally good at math, have a hard time with fractions. If you fall in this category, there is hope. By following these simple tips for fractions, you can learn how to perform basic math functions using fractions. Numerator vs. Denominator A fraction represents a part of a whole number. If you have one half (i.e., 1/2) of a pie, for example, the whole pie has been divided into two equal parts, one of which is missing. The number on the bottom of the fraction is the number of parts or the denominator. The top number is how many of the parts are present, or the numerator.
