How to identified and calculate fractional algebraic

To identify and calculate fractional algebraic expressions, you need to follow these steps:

1. Identify the fractional algebraic expression: Look for any expression that includes variables, constants, and operations such as addition, subtraction, multiplication, and division. The presence of fractions within the expression makes it a fractional algebraic expression.

2. Simplify the expression: Combine like terms, factor out common factors, and simplify fractions within the expression to make it easier to work with.

3. Calculate the expression: Once you have simplified the expression, you can calculate it by substituting numerical values for the variables and performing the necessary operations.

4. Keep the answer in fractional form: If the original expression had fractions, the final answer should also be expressed as a fraction unless stated otherwise.

For example, let's consider the fractional algebraic expression (3x + 1)/(2x - 5). To calculate this expression for a specific value of x, let's say x = 2:

(3(2) + 1)/(2(2) - 5)
= (6 + 1)/(4 - 5)
= 7/(-1)
= -7

Therefore, the value of the fractional algebraic expression (3x + 1)/(2x - 5) when x = 2 is -7.
