A fraction is a mathematical expression that represents a part of a whole. It consists of two numbers separated by a line. The top number is called the numerator, and the bottom number is called the denominator. For example, the fraction 1/2 represents one-half of a whole.
Calculators can be used to perform various mathematical operations, including fractions. To enter a fraction into a calculator, simply type in the numerator, press the divide key (/), and then type in the denominator. For example, to enter the fraction 1/2 into a calculator, you would type 1 / 2.
