In this lesson, we learned that a fraction is an equal part of a whole, written as a ratio of two numbers: the numerator and denominator. The numerator tells us how many of these equal parts we're concerned with, while the denominator tells us how many parts the whole is divided into. Fractions are commonly used in cooking, measurement, and maps. It's important to always relate fractions to the whole thing and understand their essential concepts.
