How To Simplify Divide Fractions With Variables
Repeat this process until there is no common factor left. Turn the second fraction the one you want to divide by upside down this is now a reciprocal.

This math video tutorial explains the process of dividing fractions with variables and exponents in addition to simplifying algebraic fractions.
How to simplify divide fractions with variables. If needed factor the numerator and denominator into prime numbers. Divide numerator and denominator separately with that common factor. Apply the division rule of fractions by multiplying the numerator by the reciprocal or inverse of the denominator.
Reducing Fractions with Variables When you divide fractions with variables you can use the same idea as dividing numbers. Division of Algebraic Fractions To divide algebraic fractions invert the second fraction and multiply it by the first fraction. Printable worksheets for variables 4th grade pre algebra variables example sqrt variable yr 11 application maths cheat sheet easy exponents expression worksheet multiplying and dividing fractions with variables the easy way to determine Least common denominator.
Okay now we are ready to dive in. The basic ideas are very similar to simplifying numerical fractions. Rewrite the numerator and denominator to show the common factors.
We present examples on how to simplify complex fractions including variables along with their detailed solutions. Find a factor which is common to both numerator and denominator. Multiply the first fraction by that reciprocal Step 3.
Find a common denominator by multiplying the two denominators together. Create a single fraction in the numerator and denominator. Simplify the fraction if needed.
Dfrac2x dfrac35 Solution to Example 1 The denominator x is not known and in general we assume that it is not equal to the denominator 5 of the fraction dfrac35. In order to simplify a fraction we should follow the following steps. Simplify using the equivalent fractions property by removing common factors.
The steps we follow to subtract fractions with variables are as follows. 4 62 x x x x x 1 x x x x x x x x 2 72 5 1 x x x x x x x x x x x x x x x x Notice that you can subtract the exponents to get the result in the final answer. Simplify the new fraction by finding the greatest common factor.
Factorise the numerators and denominators. So lets say we want to add 5x and 3xSince both of these fractions have whats called a common denominator we can just add. Find the greatest common factor GCF of the numerator and denominator and divide both by this number to simplify.
Variables As Part of the Fraction. Example 1 Add the fractions. Then cancel the factors common to both the numerator and denominator before applying multiplication to obtain the answer.
We now have a single simple fraction so all that remains is to render it in the simplest terms possible. Multiply any remaining factors.
