## Detailed calculations below:

### Introduction. Fractions

#### A fraction consists of two numbers and a fraction bar: ^{182}/_{61,990}

#### The number above the bar is the numerator: 182

#### The number below the bar is the denominator: 61,990

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

^{182}/_{61,990} = 182 ÷ 61,990

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

Value = 182 ÷ 61,990

### 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.

#### 182 = 2 × 7 × 13;

182 is not a prime, is a composite number;

#### 61,990 = 2 × 5 × 6,199;

61,990 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 (182; 61,990) = 2

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

^{182}/_{61,990} =

^{(2 × 7 × 13)}/_{(2 × 5 × 6,199)} =

^{((2 × 7 × 13) ÷ 2)} / _{((2 × 5 × 6,199) ÷ 2)} =

^{(7 × 13)}/_{(5 × 6,199)} =

^{91}/_{30,995}

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

^{91}/_{30,995} 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:

^{91}/_{30,995} =

#### 91 ÷ 30,995 ≈

#### 0.002935957412 ≈

#### 0

### As a percentage:

#### 0.002935957412 =

#### 0.002935957412 × ^{100}/_{100} =

#### ^{0.293595741249}/_{100} =

#### 0.293595741249% ≈

#### 0.29%

#### In other words:

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

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

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