## Reduce: ^{28,379}/_{25,563}

## Detailed calculations below:

### Introduction. Fractions

#### A fraction consists of two numbers and a fraction bar: ^{28,379}/_{25,563}

#### The number above the bar is the numerator: 28,379

#### The number below the bar is the denominator: 25,563

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

^{28,379}/_{25,563} = 28,379 ÷ 25,563

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

Value = 28,379 ÷ 25,563

### 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.

#### 28,379 = 13 × 37 × 59;

28,379 is not a prime, is a composite number;

#### 25,563 = 3 × 8,521;

25,563 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).

#### But the two numbers have no common prime factors.

#### gcf, hcf, gcd (28,379; 25,563) = 1

coprime numbers (relatively prime)

## Fraction's numerator and denominator are coprime numbers (no common prime factors). Fraction cannot be reduced (simplified) - irreducible.

^{28,379}/_{25,563} is an improper fraction.

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

## 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.

#### 28,379 ÷ 25,563 = 1 and remainder = 2,816 =>

#### 28,379 = 1 × 25,563 + 2,816 =>

^{28,379}/_{25,563} =

^{(1 × 25,563 + 2816)} / _{25,563} =

^{(1 × 25,563)} / _{25,563} + ^{2816} / _{25,563} =

#### 1 + ^{2,816}/_{25,563} =

#### 1 ^{2,816}/_{25,563}

### As a decimal number:

#### 1 ^{2,816}/_{25,563} =

#### 1 + ^{2,816}/_{25,563} =

#### 1 + 2,816 ÷ 25,563 ≈

#### 1.11015921449 ≈

#### 1.11

### As a percentage:

#### 1.11015921449 =

#### 1.11015921449 × ^{100}/_{100} =

#### ^{111.015921448969}/_{100} =

#### 111.015921448969% ≈

#### 111.02%

#### In other words:

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

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

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