## Reduce: ^{4,250}/_{30}

## Detailed calculations below:

### Introduction. Fractions

#### A fraction consists of two numbers and a fraction bar: ^{4,250}/_{30}

#### The number above the bar is the numerator: 4,250

#### The number below the bar is the denominator: 30

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

^{4,250}/_{30} = 4,250 ÷ 30

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

Value = 4,250 ÷ 30

### 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.

#### 4,250 = 2 × 5^{3} × 17;

4,250 is not a prime, is a composite number;

#### 30 = 2 × 3 × 5;

30 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 (4,250; 30) = 2 × 5 = 10

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

^{4,250}/_{30} =

^{(2 × 53 × 17)}/_{(2 × 3 × 5)} =

^{((2 × 53 × 17) ÷ (2 × 5))} / _{((2 × 3 × 5) ÷ (2 × 5))} =

^{(52 × 17)}/_{3} =

^{425}/_{3}

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

^{425}/_{3} 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.

#### 425 ÷ 3 = 141 and remainder = 2 =>

#### 425 = 141 × 3 + 2 =>

^{425}/_{3} =

^{(141 × 3 + 2)} / _{3} =

^{(141 × 3)} / _{3} + ^{2} / _{3} =

#### 141 + ^{2}/_{3} =

#### 141 ^{2}/_{3}

### As a decimal number:

#### 141 ^{2}/_{3} =

#### 141 + ^{2}/_{3} =

#### 141 + 2 ÷ 3 ≈

#### 141.666666666667 ≈

#### 141.67

### As a percentage:

#### 141.666666666667 =

#### 141.666666666667 × ^{100}/_{100} =

#### ^{14,166.666666666667}/_{100} =

#### 14,166.666666666667% ≈

#### 14,166.67%

#### In other words:

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

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

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