How To: Reduce and simplify fractions

In this tutorial, we learn how to reduce and simplify fractions. When you do this, you want to make sure you have taken common factors out of the top and bottom, then divide them out until the only common factor is the number one. You will keep going until you get to this point, or you can do another method by finding the greatest common factor. To understand this better, take the example of 24/64. The greatest common factor of these numbers is 8, because it divides evenly into both of them. ...

How To: Factor trinomials with 2 variables & GCF by grouping

In the video, the process of factoring trinomials is described. A trinomial that cannot be easily factored in its original form is shown. It is simplified by pulling out the greatest common factor. After that, a trinomial that is easier to factor is shown. Next, the simplified trinomial is broken up into four terms so that factoring by grouping can be done. Once again, a common factor from each pair is taken so that two binomials are created. Once the greatest common factor is added back with...

How To: Solve rational equations easily

This video revolves around solving rational equations in Algebra 2. When you are given a rational equation, you have to find the greatest common factor and multiply all fractions to get that common factor. If a fraction already has that common factor, then no further step is necessary for that one. Next, you have to multiply all fractions by the greatest common factor to get rid of all denominators. Finally, the remaining equation is simple math and you only need to solve the equation for the...

How To: Calculate a limit by getting a common denominator

This video explores how to get the limit by getting a common denominator. When you try and plug in a limit, for example when the denominator goes to zero, you can get yourself into a situation where you get the answer (0/0) which is mathematically irrelevant. To solve this problem, you must find a common denominator and split the problem up into its various parts. By setting common denominators in the numerator, you can then flip the fraction around allowing you to properly calculate the limi...

How To: Add rational expressions

This is the video about how to add a rational expression. So to add a rational expression first of all find the common denominator. To find the common denominator, just find the least common multiple (LCM) of the denominators. There are at least a couple ways of doing this. To convert each fraction to the common denominator, you multiply each denominator by what it needs in order to turn it into 6x. For instance, in the x+4/5x, the denominator needs to be multiplied by 6x, since 6xX5x = 30x. ...

How To: Solve & find the least common multiple

This is a mathematical instructional video on how to find the least common multiple. Let us now find the least common multiple for 25, 100, 18. This can be written as 5 square, 2 square multiplied by 5 square, 2 multiplied by 3 square. The highest factor in these numbers are, 5 square, 2 square and square. If you multiply 5 square with 2 square and 3 square you will get the final answer as 900. This is the least common multiple of 25, 100, and 18. This method is explained very clearly in this...

How To: Solve for fractions with common denominators

This a simple video illustrating the process of addition involving fractions which have common denominators. The method is really quite easy and straightforward, as demonstrated by this video. One has to simply take the denominator of the sum as the same which is the common denominator of the two fractions being added. Then, one has to take the two numerators, add the, and write their sum as the numerator of the fraction which forms the sum. Finally, the resultant fraction should be reduced b...

How To: Check and replace belts in your automobile

Many of your cars engines critical components are driven by belts. Belts operate in tough conditions, such as high heat, high speed, and are under considerable tension. Since rubber is an unpredictable material, even under ideal conditions, belt failure is one of the most common causes of auto breakdowns on the road. Vehicle belts are easy to check, like serpentine, drive, and multi rib belts, and to replace them at home is relatively easy and inexpensive. This is the best way to take care of...

How To: Understand equivalent fractions

In this video the instructor teaches about equivalent fractions. When given a problem to determine if two fractions are equivalent fractions the first thing to do is write them in the lowest terms. A fraction is said to be in the lowest terms if the greatest common divisor of both numerator and denominator is one. So cancel the common factors in the numerator and the denominator till you arrive at the lowest form and finally compare them to determine if they are equivalent. An equivalent frac...

How To: Reduce fractions

This video shows you how to easily reduce fractions. A fraction contains a numerator and a denominator. The numerator is the number on the top and the denominator is the number at the bottom of the fraction. The first thing you have to do to reduce fractions is look for the greatest common factor between the numerator and the denominator and divide both top and bottom of the fraction by that common factor. (e.g.. 18/24 - the greatest common factor is 6 => (18/6)/(24/6)= 3/4. Continue reducing...
