# Fraction (mathematics)

### From Simple English Wikipedia, the free encyclopedia

A cake with one quarter removed. The remaining 3⁄4 of the cake has been divided into two pieces

A fraction is a mathematical expression relating two quantities or numbers, one divided by the other. The numbers must be whole numbers (or integers). For example, 1/2 is a fraction.

Mathematically, a fraction is a quotient of numbers, representing the number's value when the numerator is divided by the denominator. Thus 1⁄2 means one divided by two, or, in decimals, 0.5.

If you want to have 1⁄2 of 1⁄2, you have to multiply the denominators. That means: denominator 2 multiplied by 2 equals 4 or: 1⁄2 x 1⁄2 = 1⁄4 or: 0.5 x 0.5 = 0.25

(In this case “1⁄2 of” means mathematically "multiplication".)

If you want to have 1⁄2 divided by 1⁄2, then you have to multiply 1⁄2 and the reciprocal of 1⁄2, which is 2. Thus, that answer is 1.
