Fractions: What’s the Word? Fraction basics: A fraction is a part of a whole. Watch to learn more about numerators (the top number) and denominators (the number on the bottom). A fraction can be represented as any parts of a whole. Some fractions are more common than others, like 1/2, 1/3, 1/10, etc.
Fractions, Decimals and Percentages Fractions refer to how many equal parts there are in a whole. Decimals and percent are easier ways to compare fractions and numbers with each other, especially when working with unlike denominators. Also, learn to convert fractions using division to get a decimal number.
