Fractions

Definition Fraction is a number written with a numerator and a denominator, in which both are natural numbers. Numerator: the top number of fraction Denominator: the top bottom of fraction So, fraction is written as Numerator / Denominator Examples Fraction Numerator Denominator 1 2 2 3 3 4 7 40 99 123 Learn More Simplest

Simplest Form of Fractions

Simplest form of A fraction is a fraction that has the top and bottom cannot be any smaller (simplified), while still being whole numbers. How to simplify a fraction? Divide the top and bottom by the greatest number that will divide both numbers exactly (Greatest Common Factor), they must stay whole numbers. Examples Fraction Greatest

Basic Math Definitions

Basic Math Operations In basic mathematics, there are many ways of saying the same thing: Symbol Definitions + Addition, Add, Increase, Plus, Sum, Total − Decrease, Deduct, Difference, Less, Minus, Subtraction, Subtract, Take Away × Multiplication, Multiply, Times, Product, By, Lots Of ÷ Division, Divide, Goes Into, How Many Times, Quotient Addition Addition is bringing two or more numbers (or things)

Inverse Operation

Inverse Operation is an operation that reverses or undo the effect of another operation. Definition of Inverse Operation What are Inverse Operations? Inverse means reverse in position / direction. The word “inverse” comes from the Latin word “inversus” which means to turn inside out or upside down. Inverse operation in mathematics is an operation that undoes what was done by the previous operation. Most

Difference

Definition Difference is the result of subtracting one number from another. How much one number differs from another. More Examples Here are more examples about difference: Numbers Difference Reason 7 and 5 2 7 – 5 = 2 4 and 9 5 9 – 4 = 5 11 and 8 3 11 – 8 =

Multiplicative Inverse

Multiplicative Inverse is Another name for Reciprocal. What you multiply by a number to get 1 In other words: When we multiply a number by its “Multiplicative Inverse” we get 1. But not when the number is 0 because 1/0 is undefined! More Examples of Multiplicative Inverse Number Multiplicative inverse 2 1/2 3 1/3 5

Additive Inverse

Definition of Additive Inverse The additive inverse of a number is another number you add to a number to create the sum of zero. In other words, additive inverse of x is another number, for examle y, as long as the sum of x + y equals zero. The additive inverse of x is equal

Equivalent Fractions

Equivalent Fractions have the same value, even though they may look different. These fractions are really the same: Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it’s value. The rule to remember is: “Change the bottom using multiply or divide,

Least Common Denominator

What is a Denominator? The denominator is the bottom number in a fraction. It shows how many equal parts the item is divided into Common Denominator? When the denominators of 2 or more fractions are the same, they have Common Denominators. Finding a Common Denominator One simple answer is to multiply the current denominators together.
