How to reduce (simplify) fraction 908/916,000 to lowest terms? Write it as a proper fraction, a decimal number, a percentage

Reduce: 908/916,000

Detailed calculations below:

Introduction. Fractions

A fraction consists of two numbers and a fraction bar: 908/916,000


The number above the bar is the numerator: 908


The number below the bar is the denominator: 916,000


The fraction bar means that the two numbers are dividing themselves:
908/916,000 = 908 ÷ 916,000


Divide the numerator by the denominator to get fraction's value:
Value = 908 ÷ 916,000


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.


908 = 22 × 227;
908 is not a prime, is a composite number;


916,000 = 25 × 53 × 229;
916,000 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 (908; 916,000) = 22 = 4



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

908/916,000 =


(22 × 227)/(25 × 53 × 229) =


((22 × 227) ÷ 22) / ((25 × 53 × 229) ÷ 22) =


227/(23 × 53 × 229) =


227/229,000


The fraction is now reduced to the lowest terms.

227/229,000 is a proper fraction.

A proper fraction: numerator smaller than denominator.

Tutoring: simplifying ordinary math fractions (reducing to the lowest terms)

Steps to simplify an ordinary fraction, to reduce it to its lowest terms:

  • 1) Factor both the numerator and the denominator of the fraction into prime factors.
  • 2) Calculate the greatest common factor, GCF (or the greatest common divisor, GCD) of the fraction's numerator and denominator.
  • 3) Divide both the numerator and the denominator of the fraction by the greatest common factor, GCF (GCD).
  • In conclusion: the fraction thus obtained is called a reduced fraction or a fraction simplified to its lowest terms.
  • A fraction reduced to its lowest terms cannot be further reduced and it is called an irreducible fraction.

Why reducing (simplifying) fractions to lower terms?

  • When running operations with fractions we are often required to bring them to the same denominator, for example when adding, subtracting or comparing.
  • Sometimes both the numerators and the denominators of those fractions are large numbers and doing calculations with such numbers could be difficult.
  • By simplifying (reducing) a fraction, both the numerator and denominator of a fraction are reduced to smaller values. Well, these values are much easier to work with, reducing the overall effort of working with fractions.
