One-tenth is a fraction that represents one part out of ten equal parts. It is written as 1/10 and can also be expressed as a decimal, which is 0.1. This concept is commonly used in mathematics to help understand proportions and divisions of whole numbers. In everyday life, one-tenth can be seen in various contexts, such as when dividing a pizza into ten equal slices. If someone eats one slice, they have consumed one-tenth of the pizza. This idea is also important in finance, where one-tenth can represent a percentage, specifically 10%, of a total amount, such as money or resources.
