Three fourths, often written as 3/4, is a fraction that represents three parts out of a total of four equal parts. It is commonly used in everyday situations, such as cooking or measuring, where items are divided into equal sections. For example, if a pizza is cut into four equal slices, three slices would represent three fourths of the pizza. In mathematical terms, 3/4 can also be expressed as a decimal, which is 0.75. This means that three fourths is equivalent to seventy-five hundredths. Understanding fractions like 3/4 is essential for basic arithmetic and helps in comparing quantities and solving problems involving parts of a whole.
