Two-fifths is a way to express a fraction, specifically the part of a whole that is divided into five equal parts, with two of those parts being considered. In numerical terms, two-fifths is written as 2/5. This means that if you have something divided into five equal sections, two-fifths represents two of those sections. In practical terms, two-fifths can be used in various situations, such as cooking or measuring. For example, if a recipe calls for two-fifths of a cup of sugar, you would measure out two parts from a total of five equal parts of sugar. This concept helps in understanding proportions and ratios in everyday life.
