Title: Comparing Fractions to 1 - Fast And Easy Math Learning Videos

In this lesson, you will learn when a fraction is less than one whole unit, equal to one whole unit, or more than one whole unit. A fraction equals one whole unit when the numerator and denominator are the same. This example shows us that two-thirds does not equal one. The numerator and denominator are not the same.
Here's another example of a fraction that does not equal one. Five-thirds does not equal one. The numerator and denominator are not the same.
Now let's look at a fraction that does equal one whole unit. Three-thirds equals one. The numerator and denominator are the same.
Here's another example of a fraction that is equal to one. Six-sixths equals one. The numerator and denominator are the same.
Now let's take look at fractions that are less than one and more than one. Four-sixths is less than one. A fraction is less than one when the numerator is less than the denominator.
Here's an example of a fraction that is more than one. Fifteen-sixths is more than one. A fraction is more than one when the numerator is more than the denominator.
Now try a few problems on your own. To solve this problem, you must click on the correct answer, like this.
The correct answer is less than. One-third is less than 1. For the problems that follow, click on the correct answer.

Title: Dividing Fractions

You know that the multiplication of both whole numbers and fractions can be represented using an array that looks like this. This example shows four-fifths multiplied by two-thirds.
The product of multiplying the fractions is eight-fifteenths.
You also know that division is just another way of writing multiplication when one of the factors is unknown. That’s easy to see using this array. Let’s assume that you know the total size of the array, which is eight-fifteenths, and you know one of the factors in the multiplication, four-fifths.
But you don’t know the other factor, which we’ll now call X.
X is the number you need to multiply by four-fifths to get eight-fifteenths.
We can represent this situation with two different number sentences.
The first number sentence is written as multiplication. We know that four-fifths is multiplied by some number on this side called X.
And the result is eight-fifteenths.
We can also describe exactly the same situation with a division number sentence like this.
We know that we have eight-fifteenths, which is divided by four-fifths.
But we don’t know the length of this side of the array, which is the value for X.
So, these equations tell us exactly the same thing because they represent the same situation shown by the array.
The X in both equations represents the same number – it’s the missing value for the length of one side of the array.
While this array is helpful in seeing what a division problem represents, it’s not very helpful in finding out the number we need on this side, because we don’t know how many parts to divide each whole unit into. So how do we find this number? The best way is to use what we know about algebraic reasoning, using these two equations to describe the array.
We’ll start by finding the value of X in the multiplication equation.
This will help us later in understanding how to solve the division equation.
You know that you can multiply both sides of an equation by the same number and it doesn’t change the equation. We can use this to our advantage if we choose the right number to multiply by. We want a number that will give us one X instead of four-fifths X on the left side of the equation.
You know that multiplying any number by its reciprocal gives you 1. Let’s multiply fourth-fifths by its reciprocal like this.
Five-fourths times four-fifths is one, so the left side of the equation now becomes 1 times X, which we write as just X. You also know that if you multiply one side of an equation by a number you have to multiply the other side by the same number.
So, we multiply the right side of the equation by five-fourths.
When we multiply, we get forty-sixtieths.
We can divide both terms by 20, to see that X equals two thirds.
When we compare this to the multiplication problem we started with, we see that two-thirds is the correct answer, because two-thirds times fourth-fifths is indeed eight-fifteenths.
But how does this help us understand how to divide fractions? It’s actually very simple. Let’s look at these two statements from the equations.
Remember that X represents the same number in both equations. It’s the length of this line in the aray.
The equation on the right says you can find X by dividing eight-fifteenths by four-fifths. The eqution on the left says you can find X by multiplying eight-fifteenths by the reciprocal of four-fifths.
Using what you already know about algebra, you can prove that this same approach always works, but we won’t go through that proof here. It means that dividing any number by a fraction and multiplying that number by its reciprocal gives you the same result.
We’ll just look at a couple of examples to verify that this works.
We’ll start with this multiplication statement. Three-fourths times five-eighths equals fifteen-thirty-seconds.

The MAD is the average distance of all of the elements in a data set from the mean of the same data set
You can think of it as how far each piece of information is from the average
If you look at MAD you have the mean which is the average, the absolute value, and deviation.
The MAD indicates how spread out your data set is.
A large MAD indicates a data set more spread out relative to the mean.
A small MAD indicates a data set less spread out relative to the mean.

This video helps with the following Math Standard
MGSE9-12.S.ID.2 Use statistics appropriate to the shape of the data distribution to compare center
(median, mean) and spread (interquartile range, mean absolute deviation, standard deviation) of
two or more different data sets.

This lesson covers solving systems of equations by graphing. Students learn to solve a system of linear equations by graphing. The first step is to graph each of the given equations, then find the point of intersection of the two lines, which is the solution to the system of equations. If the two lines are parallel, then the solution to the system is the null set. If the two given equations represent the same line, then the solution to the system is the equation of that line.

Biodiversity and ecosystems.
Biodiversity is the variety of life in an area that is determined by the number of species in that area. In simple terms “ Biodiversity is the number of different individuals and life forms in an area.
As biodiversity increases so do the health of the ecosystem increases.
Think of it as if you were running a business.
You want your business to be healthy and make money. Imagine you sell shirts. If you only sold a black shirt with a heart you are limited and if these shirts go out of style you are out of business. If you have a variety of shirts as fashion changes you are better able to adapt to these changes and continue to make money.
As biodiversity increases the ecosystem has a greater ability to adapt to changes.
and a healthy ecosystem has a greater chance of recovering from disasters.
Biodiversity can be broken down into three types
Genetic diversity
Species diversity
Ecosystem diversity

Step-by-Step Technique on How To Solve Quadratic Equations by Completing the Square. By PreMath.com

In this video I will show you how to solve a rational equation for x. This example involves two rational expressions that are being subtracted and set equal to zero.

When solving rational equations, you need to multiply by some factor to cancel out the denominator. Doing this will simplify your rational equation greatly, and allow you to use basic algebraic strategies such as FOIL and the distributive property to solve for x.
