"Half" refers to one of two equal parts of a whole. For example, if you have a pizza and cut it into two equal slices, each slice represents half of the pizza. This concept is important in everyday life, such as when sharing food or dividing tasks. In mathematics, "half" is often represented as the fraction 1/2. It can also be expressed as a decimal, which is 0.5. Understanding halves helps us with measurements, cooking, and even budgeting, making it a fundamental concept in both math and daily activities.
