A complex fraction is a fraction in which the numerator or numerator contains one or more fractions. is a fraction in which the numerator or numerator contains one or more fractions. For instance,
To simplify such a fraction, we need to find an equivalent fraction with a numerator and a denominator. One way to do this is to divide. Remember that dividing a fraction involves multiplying the inverse of the divisor.

Another way to simplify this complex fraction is to multiply both the numerator and the denominator of the LCD by all given fractions. In this case, LCD = 4.
A complex rational expression is a rational expression in which the numerator or denominator contains one or more rational expressions. is defined as a logical expression that contains one or more logical expressions in an enumerator or an evalator or both. For instance,
We simplify a complex rational expression by finding an equivalent fraction where the numerator and denominator are multiples. As mentioned above, there are two ways to simplify complex logical expressions, and we will explain the steps in both ways. For clarity, assume that the variable expression used as the evaluator is zero.

We begin our discussion of simplifying complex logical expressions using division. Before we multiply the divisor, we need to simplify the multiplication and division separately. The goal is to first find an algebraic fraction in the numerator and denominator. The steps for simplifying a complex algebraic fraction are shown in the following example.
Step 1: Simplify the numerator and denominator. The goal is to find an algebraic fraction and divide it by another algebraic fraction. In this example, before addition and subtraction, find equivalent terms that have a common denominator for both multiplication and division.
Solution: On the LCD, the rational expression for both the numerator and denominator is x2. Click on the appropriate factors to find the corresponding words and this value and then subtract it.

Now we have a rational expression divided by another rational expression. Then, multiply the numbers through the divisor and then subtract and cancel.
Another way to simplify complex rational expressions is to clear fractions by multiplying the special form expression by 1. In this method, add the numerator and the least common denominator (LCD) of all the given fractions.
Step 1: Determine the LCD of all the fractions in the numerator and denominator. In this case, the values of the given fractions are 2, x, 4 and x2. So, LCD is 4×2.
Solution: Complex Fractions
Step 2: Enter the number and name on the LCD. This step should clear the fractions in both the numerator and denominator.
This leaves us with an algebraic fraction containing many numbers and digits.
This was the same problem that started this chapter, and the results here are the same. It is worth taking the time to compare the steps involved in using both methods for the same problem.
Math 7 1 2 Complex Fractions
Solution: Based on all the values, we see that the LCD is x2. So, multiply the numerator and denominator by x2:
At this point, we have a logical expression that makes it easy to isolate and then eliminate common problems.
It is important to note that multiplying the numerator and denominator by the same non-zero factor is the same as multiplying by 1 and does not change the problem. Since x2x2=1, we can multiply the numerator and denominator of x2 in the previous example and get an equivalent expression.

Composite fractions are fractions in which either the numerator, the divisor, or both are themselves fractions. For this reason sometimes solid fractions are called “stacked fractions”. Simplifying complex fractions is a process that ranges from easy to difficult based on how many terms in the numerator and denominator, whether any of them are variables, and if so, the complexity of the variable terms. See step 1 below to get started!

To simplify complex fractions, start by finding the lowest contrast you can do by simply inverting the fraction. Then, add this new fraction to the numerator. You should now have one simple chip. Finally, by finding the largest factor between the numerator and denominator, simplify the new fraction and divide both parts by this number.

Complex Fractions Graphic Organizer Notes
A complex number is a number that combines a real part with an imaginary part. Imaginary is the term used for the square root of a negative number, especially the symbol i=−1}}. A complex number consists of prime numbers and multiple i’s. Some examples of complex numbers are 3+2i, 4-i, or 18+5i. Complex numbers, like other numbers, can be added, subtracted, multiplied or divided and then the expressions can be simplified. You must use special rules to simplify these complex numerical expressions.
