## Detailed calculations below:

### Introduction. Fractions

#### A fraction consists of two numbers and a fraction bar: ^{57}/_{99,332}

#### The number above the bar is the numerator: 57

#### The number below the bar is the denominator: 99,332

#### The fraction bar means that the two numbers are dividing themselves:

^{57}/_{99,332} = 57 ÷ 99,332

#### Divide the numerator by the denominator to get fraction's value:

Value = 57 ÷ 99,332

### Introduction. Percent

#### 'Percent (%)' means 'out of one hundred':

#### p% = p 'out of one hundred',

#### p% = ^{p}/_{100} = p ÷ 100

### Note:

#### The fraction ^{100}/_{100} = 100 ÷ 100 = 100% = 1

#### Multiply a number by the fraction ^{100}/_{100},

... and its value doesn't change.

## To reduce a fraction, divide both its numerator and denominator by their greatest common factor, GCF.

#### To calculate the greatest common factor, we build the prime factorization of the two numbers.

### Integer numbers prime factorization:

#### Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

#### 57 = 3 × 19;

57 is not a prime, is a composite number;

#### 99,332 = 2^{2} × 19 × 1,307;

99,332 is not a prime, is a composite number;

** Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself. *

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

### Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:

#### Multiply all the common prime factors, by the lowest exponents (if any).

#### gcf, hcf, gcd (57; 99,332) = 19

### Divide both the numerator and the denominator by their greatest common factor.

^{57}/_{99,332} =

^{(3 × 19)}/_{(22 × 19 × 1,307)} =

^{((3 × 19) ÷ 19)} / _{((22 × 19 × 1,307) ÷ 19)} =

^{3}/_{(22 × 1,307)} =

^{3}/_{5,228}

## The fraction is now reduced to the lowest terms.

^{3}/_{5,228} is a proper fraction.

#### A proper fraction: numerator smaller than denominator.

## Rewrite the end result, continued below...

## Rewrite the end result:

### As a decimal number:

^{3}/_{5,228} =

#### 3 ÷ 5,228 ≈

#### 0.000573833206 ≈

#### 0

### As a percentage:

#### 0.000573833206 =

#### 0.000573833206 × ^{100}/_{100} =

#### ^{0.057383320582}/_{100} =

#### 0.057383320582% ≈

#### 0.06%

#### In other words:

#### 1) Calculate fraction's value.

#### 2) Multiply that number by 100.

#### 3) Add the percent sign % to it.
