In this video the instructor shows how to solve rational equations. If you have fractions in your equation, then you need to factorize the denominators first. Now compute the least common denominator of all the denominators of the fraction. Next multiply both sides of the equation with the least common denominator. This cancels out all the denominators of all the fractions and you are left with a linear equation. Now simply multiply the remaining terms in the numerator and add common terms to...
In this video the instructor shows how to add and subtract rational expressions. When you have an addition or subtraction problem of rational expressions, first look and compare the denominator of all the terms. If all of them have the same denominator then the expression can be written as a fraction whose denominator is the original common denominator and whose numerator is the sum of numerators of all the other terms. Simplifying the numerator by adding and subtracting the like terms gives ...
This video shows the method to add rational expressions with different denominators. The first step in this process involves finding the LCD. After this is done, the numerator and denominator are multiplied by a specific number so that the fractions are rewritten with common denominators. In the second step the numerators are added or subtracted according to the problem with LCD in the denominator. Simplify the numerator by adding or subtracting like terms. After this, we get a rational expre...
In this tutorial the instructor shows how to factor a trinomial with Greatest Common Factor (GCF) and then how to group it. The first thing you have to do when you want to factor a trinomial is look for the GCF. First factor the numerical coefficients of the terms of the equation. Now separate out the common numerical factor and if any common variable. This leaves you with a binomial to be factored. Now to solve this multiply the numerical coefficients of the first term and the last term and ...
This video tutorial shows you the proper way to find the GCF, or greatest common factor. While this is not necessary, the video shows a method of drawing a T chart. List both the numbers that you need to find the GCF, then list there factors, including the number 1. Once you display your factors of both numbers it is a clear cut visual of what the GCF is. In the case of the problem on the video the number 4 has factors of: 1, 2, 4 and the number 20 has factors of: 1, 2, 4, 5, 10, and 20. Ther...
This video shows you how to easily add two fractions with uncommon denominators. To add the two fractions you must translate the fractions into its higher equivalent form, with a common denominator. To find a common denominator, you must find the lowest multiple that both denominators can go into. You must multiply both the numerator and the denominator by a number, so that the denominator can go into the lowest common multiple you found earlier. Then, simply add the numerators and keep the s...
This is a video that teaches how to add and subtract fractions. For fractions that have like denominators, you simply add the numerator and keep the denominator. Next, you reduce the fraction to its lowest term.
In this tutorial the instructor shows how to subtract mixed numbers with common denominators. He explains the method using an example. He does this by subtracting the whole numbers separately and also subtracts the fraction parts separately. Now he finally puts both those results side by side and if the obtained result is not further deductible, it gives us a new whole number which is our desired result. If you want to learn how to subtract mixed numbers with common denominators watch this tu...
A simple video showing how to subtract fractions with common denominators. The denominators is the bottom number of a fraction and the numerator is the top number. So in the fraction of one half 1 is the numerator and 2 is the denominator. If you have fractions with same denominator you can subtract the numerators to find the difference. After the subtracting the numerators add the common denominator to complete the fraction. So five sevenths subtracted by one seventh equals four sevenths. If...
Watchers of this video will learn how to find the "lowest common multiple", the lowest whole number that can be divided by each of two numbers evenly. For example, the lowest common multiple of 8 and 12 is the lowest number of which 8 and 12 are both factors. To find the lowest common multiple of 2 numbers, find the factors of both numbers. One way to do this is to make a "factor tree", drawing branches with factors from each number until it cannot be factored any more. Once both numbers are ...

This video instructs on how to find the sum of fractions that have the same denominator. In order to do this, all that needs to be done is to add the different numerators together, then put the sum of those numbers over the common denominator. The example used is 2/9 + 1/9 + 5/9. The first step is to add the numerators which gives you 2 + 1 + 5/9. Then simplify the fraction adding 2 + 1 + 5 which equals 8. That is your numerator. The denominator does not change because it is common, so the fi...
