**FRACTION DECIMAL AND PERCENT CYCLE**

Fraction

Fraction is a part of a whole.

the number on top is called the numerator, and the number on the bottom of a fraction is called the denominator.

The numerator stands for the number of parts you have, and the denominator stands for the number of parts the whole is divided into.

Improper Fractions

Improper fractions is a type of fraction where the value of the numerator is greater than the denominator. for example: 6/3 is a improper fraction because 6 is greater than 3

Equivalent Fraction

The equivalent fraction is when two or more fractions have the same value. The number of the Numerator and the denominator of the fractions doesn't have to be the same. For Example: 3/6 and 1/2 is an equivalent fractions because 3/6 worth one half of a fraction adn 1/2 also worth one half of an fraction

Proper fraction

An proper fraction is where the denominator is greater than the numerator. The whole number also counts as the proper fractions. For example: 1/3 and 2 3/4

Methods

Adding fractions

To add fractions, if the denominator of the fractions are the same, add the numerators together and the denominator of the answer remain the same. If the denominators of the fractions are different, times the denominators together, and then time both the denominator and the numerators with the other fraction's denominators. Then you will get the equivalent denominator and add the numerator together.

converting fraction into percentage

To convert fraction into a percentage is to divide the numerator by the denominator. Then multiply the anwser by 100.

**Subtracting Fraction**

Example

**Method**

If the denominator of both fractions are the same, subtract the numerator of both fractions together.

If the numerator of the fractions are not the same, then multiply the numerator and the denominator of each fraction with the opposite denominator. Then you should get the equivalent denominator.

Multiply Fraction

Example

Method

To multiply fractions is to multiply the numerators of the two fractions together and to multiply the denominator of both fractions together.

This method can also be known as to multiply the numbers straight across.

Dividing Fraction

Method

To divide fractions change the operation to multiplication and reciprocate the second fraction. Then multiply the fractions normally.

Converting standard form to scientific notation

Method

If we convert standard form to scientific notation and the 10 has negative value, move the decimal to the left. If it is positive move the decimal to the right.

Example

4.91 x 10

Converting scientific notation into a standard form

Method

Example

to convert scientific notation into a standard form, if the 10 has the negative value move the decimal to the left, if it has positive value move the decimal to the right.
