Multiply and Simplify Fractions

In this math tutorial, you will learn how to reduce fractions using the prime factoring method. The narrator, a math teacher, of the video begins by defining what prime numbers are. This is important to know. When reducing fractions you need to reduce both the numerator and th ...more

A representative from Math Problem Generator explains in this video that converting a simple fraction from its current state to a higher equivalent can be very simple. He explains the process neatly and provides a great example. To convert a fraction, you must multiply the num ...more

This video will show those who would like to learn more about math how to easily compare fractions with different denominators using a simple technique. You will be able to compare the fractions to each other by multiplying the numerator of each fraction with the denominator o ...more

In this tutorial the instructor explains how to divide fractions. He gives a three step approach where in the first step we take the reciprocal of the second fraction. In the second step the newly arrived at fraction is multiplied with the original fraction. Now finally in ste ...more

In this math lesson we will learn how to solve a proportion word problem. Watch the video to learn how to set up a proportion, solve it, and interpret the answer. Definition A proportion is a statement that two ratios (or fractions) are equal. The cross products of the terms ...more

Watch the following video to understand the steps necessary when simplifying square roots. To simplify expressions with radicals, follow these simple steps: • Write the radicand (the number underneath the radical sign) as a product of prime numbers. For larger numbers you ca ...more

In this lesson, you will learn how to solve a probability word problem. Need help with your algebra and geometry? Well... P(event)= Number of favorable outcomes / Total number of outcomes In the above problem, the number of favorable outcomes is 4 because there are $ blue ma ...more

This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the sam ...more

This video demonstrates the quotient rule as applied to exponential expressions that appear in the form of, to use the word loosely, a fraction. The name, "quotient rule", refers to the fact that it applies to expressions which are divided by other expressions. The video begin ...more

This video teaches us the concept of nth roots. The video starts with the square root of constants. We find the number which when multiplies by itself for two times results in the constant inside the square root. Then we find the square root of variables. Here again the same c ...more

This video shows the method to change a word problem into algebra and to identify rational numbers among a group of numbers. In the first part of the video we take a word problem namely - The product of 9 and seven, less than a number. 9 multiplied by something can be expresse ...more

The gentleman, acting as the Instructor, starts the session immediately by suggesting that to teach early multiplication all parents should practice a method of "Count-by's" with their children when they are very young using ones to ten, twos to twenty, threes to thirty, fours ...more

This video describes how to divide fraction values using simple method. Example we will take as in video "12" should be divided with "1/2" that is "12%(1/2)=?". This is the example we should solve. In first step we has to flip the "Denominator" to easily find the output. So no ...more

You can't add fractions when the denominators are not the same - it's a rule in math you can't ignore! Write out the two fractions you want to add. In this video, the equation to solve looks like this: 2/3 + 4/5 = ??? Start by making a common denominator. This is easy - just ...more

Everyone has used a ruler at some point in their life, whether for art sizing, blueprint plans, or sizing up your widescreen television on your living room wall. But there's a lot of little ticks on the ruler that you may not be aware of. Your ruler shouldn’t be used only to d ...more

This video shows you how to easily divide proper fractions. In the first step, you have to calculate how many times does the denominator fit into the numerator. You need to divide the numerator by the denominator. If the denominator does not fit into the numerator, you have to ...more

This video is a simple math video showing how to add and subtract fractions using different denominators. It begins with a man explaining briefly and sitting in front of a piece of paper. He writes out a group of fractions each one with different denominators, ending in three ...more
