## Reduce: ^{48,688}/_{100}

## Detailed calculations below:

### Introduction. Fractions

#### A fraction consists of two numbers and a fraction bar: ^{48,688}/_{100}

#### The number above the bar is the numerator: 48,688

#### The number below the bar is the denominator: 100

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

^{48,688}/_{100} = 48,688 ÷ 100

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

Value = 48,688 ÷ 100

### 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.

#### 48,688 = 2^{4} × 17 × 179;

48,688 is not a prime, is a composite number;

#### 100 = 2^{2} × 5^{2};

100 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 (48,688; 100) = 2^{2} = 4

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

^{48,688}/_{100} =

^{(24 × 17 × 179)}/_{(22 × 52)} =

^{((24 × 17 × 179) ÷ 22)} / _{((22 × 52) ÷ 22)} =

^{(22 × 17 × 179)}/_{52} =

^{12,172}/_{25}

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

^{12,172}/_{25} is an improper fraction.

#### An improper fraction: numerator larger than denominator.

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

## Rewrite the fraction:

### As a mixed number (mixed fraction):

#### A mixed number (mixed fraction): a whole number and a proper fraction, of the same sign.

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

#### 12,172 ÷ 25 = 486 and remainder = 22 =>

#### 12,172 = 486 × 25 + 22 =>

^{12,172}/_{25} =

^{(486 × 25 + 22)} / _{25} =

^{(486 × 25)} / _{25} + ^{22} / _{25} =

#### 486 + ^{22}/_{25} =

#### 486 ^{22}/_{25}

### As a decimal number:

#### 486 ^{22}/_{25} =

#### 486 + ^{22}/_{25} =

#### 486 + 22 ÷ 25 =

#### 486.88

### As a percentage:

#### 486.88 =

#### 486.88 × ^{100}/_{100} =

#### ^{48,688}/_{100} =

#### 48,688%

#### In other words:

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

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

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