In algebra, one half of a number is represented as the number multiplied by 1/2, or equivalently, the number divided by 2.
Here's a breakdown:
-
Representation: If the number is represented by the variable "x", then one half of that number is expressed as (1/2) * x or x/2.
-
Explanation: Dividing a number by 2 is the same as finding half of it. The algebraic representation simply generalizes this concept for any number, represented by the variable x.
-
Examples:
- If x = 10, then x/2 = 10/2 = 5.
- If x = -4, then x/2 = -4/2 = -2.
- If x = 3.14, then x/2 = 3.14/2 = 1.57
-
General Form: For any number represented by a variable, dividing that variable by 2 gives you half of the number. This is a fundamental concept in algebra used in various equations and problem-solving scenarios.
Therefore, in algebra, finding one half of a number involves dividing the variable representing that number by 2.
