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...

How To: Swim a breaststroke faster

A common trait of really fast breaststrokers is that they initiate the pull prior to lifting their head. In contrast, a common trait of Masters swimmers is that they bring the head up too soon in breaststroke and leave it there too long. Learn how to keep your head down during the pull to swim a faster breaststroke.

News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact

As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.

How To: Create an inside out French braid/mohawk braid

You've probably never heard of or seen an inside out French braid before. Which is all the more reason you should try this tutorial! While it definitely sounds difficult, an inside out French braid is basically how a French braid would look like if you flipped it over. So rather than the braid being underneath the surface of the hair, it is on the surface of the hair instead. When braided down your head, it turns into a sort of mohawk look, only with a braid instead of spiky hair.

How To: Cut up a cabbage

This video is a demonstration of the proper way to cut up a cabbage. Large vegetables like cabbage can be hard to cut up because they are so big and tend to move around on the cutting surface. The first thing to do is to create a flat surface, so make it safer to cut. Cut the whole cabbage in half holding the end of the core on top. Cut the core out of each half in a big V shape. Cut it in half again to make quarters. Take the cabbage apart so that you can flatten it out and cut thin slices f...

How To: Make magnets float down a steel tube

Mr.G in the episode 3 of "Summer snow fall" explain the experiment for eddy currents and lenz law by using general house hold items like copper tubes of different dia., 2-neo themium magnets attached together and a ball bearing magnet. At first he took the big diameter copper tube and drop the neo-themium magnets, they fall slowly without touching the surface of the copper tube as they are like freely falling from space with less gravity, for the next time he took small diameter copper tube a...

How To: Install kitchen tile and apply grout

In this Home & Garden video tutorial you will learn how to install kitchen tile and apply grout. Take measurement of the area that is to be tiled. If you want to make a mosaic with the tiles, cut the tiles as per the design and layout the mosaic on a flat surface. Apply setting compound on the surface and fix the tiles as per the design. If there are diagonal cut, use a speed square to establish 45 degree angle. To bridge the thickness difference between glass and ceramic tiles, use the lamin...

How To: Avoid common strategic planning pitfalls

In this tutorial, we learn how to avoid common strategic planning pitfalls. First, you will need to look at all the common pitfalls. You want to have ownership for the planning process. Everyone that is involved needs to have the tools to get the goals accomplished. Lack of communication is a big problem, so have everyone on the same page with how to talk and communicate what's going on. Decision making should be scattered with different managers and they should be guiding the rest of the sta...

How To: Subtract rational expressions

In this video, we learn how to subtract rational expressions. To start, you will need to find common denominators. To do this, factor out the denominators in the fractions on both sides of the equations. Now you need to build the lowest common denominator for these two fractions. To do this, take the first denominator and take whatever is missing from the second. After you do the math for this, you will build new fractions with the common denominator as the denominator. Leave the denominator ...

How To: Add unlike fractions using basic math

In order to add unlike fraction, using basic math, you will need to find the lowest common multiples of the denominators. In order to add 5/12 and 1/6, you will need to make the denominators the same. The lowest common multiple, for these fractions is 12.

How To: Reduce a fraction by finding common factors in math

The aim of the video is to show how to reduce a fraction by factoring out prime numbers that are common to both the numerator and the denominator. The example shown in the video is 27/21. The number 27 can be achieved by multiplying 3 by 9 and the number 21 is the result of 3 multiplied by 7. The common factor, therefore in both the numerator and the denominator is 3. 3 on the top divided by 3 on the bottom is 1 and so this can be removed without affecting the value of the fraction, leaving 9...

How To: Factor polynomials by grouping

A factoring problem that has to be solved by grouping is easy to identify, because you can always identify if there are any similar terms in a polynomial. Now, if you find any variable common in any terms pull them out as the common leaving the rest of the terms. After pulling out the common terms you can group the rest of the polynomial. Be careful while pulling out signs. Pulling out a positive number does not effect the signs of terms in the polynomial, where as pulling out a negative numb...

How To: Solve rational equations

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...

How To: Add & subtract rational expressions

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 ...

How To: Add rational expressions with different denominators

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...

How To: Factor a trinomial by GCF then grouping

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 ...
