- 130/229 × 221/265 × 106/224

Simplify the operation

Reduce (simplify) the fractions to their lowest terms equivalents:

  • A fully reduced (simplified) fraction is one with the smallest possible numerator and denominator, one that can no longer be reduced, and it is called an irreducible fraction.
  • * By reducing the values ​​of the numerators and denominators of fractions, subsequent calculations become easier to perform.
  • To reduce a fraction to the lowest terms equivalent divide its numerator and denominator by their greatest common factor, GCF.

  • To calculate the GCF, factor the numerator and denominator of the fraction into prime factors.
  • Then multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponents (the lowest powers).

The fraction: 130/229

130/229 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors.


The prime factorizations of the numerator and denominator:

130 = 2 × 5 × 13

229 is a prime number (it cannot be factored into other prime factors)


GCF (130; 229) = 1


The fraction: 221/265

221/265 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors.


The prime factorizations of the numerator and denominator:

221 = 13 × 17

265 = 5 × 53


GCF (221; 265) = 1


The fraction: 106/224

The prime factorizations of the numerator and denominator:

106 = 2 × 53

224 = 25 × 7


GCF (106; 224) = 2


106/224 =

(106 ÷ 2)/(224 ÷ 2) =

53/112


Yet another method to reduce a fraction:

106/224 =


(2 × 53)/(25 × 7) =


((2 × 53) ÷ 2)/((25 × 7) ÷ 2) =


(2 ÷ 2 × 53)/(25 ÷ 2 × 7) =


(1 × 53)/(2(5 - 1) × 7) =


(1 × 53)/(24 × 7) =


53/112



Rewrite the equivalent simplified operation:

- 130/229 × 221/265 × 106/224 =


- 130/229 × 221/265 × 53/112

Perform the operation of calculating the fractions

Multiply the fractions:

Multiply the numerators, that is, all the numbers above fractions bars, separately.

Multiply the denominators, that is, all the numbers below fractions bars, separately.


* Factor all the numerators and all the denominators in order to easily reduce (simplify) the end fraction.

- 130/229 × 221/265 × 53/112 =


- (130 × 221 × 53) / (229 × 265 × 112) =


- (2 × 5 × 13 × 13 × 17 × 53) / (229 × 5 × 53 × 24 × 7) =


- (2 × 5 × 132 × 17 × 53) / (24 × 5 × 7 × 53 × 229)

Reduce (simplify) the end fraction to its lowest terms equivalent:

Calculate the greatest common factor, GCF,
of the numerator and denominator of the fraction:

  • To reduce a fraction to the lowest terms equivalent divide its numerator and denominator by their greatest common factor, GCF.

  • To calculate the GCF, factor the numerator and denominator of the fraction into prime factors.
  • Then multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponents (the lowest powers).

GCF (2 × 5 × 132 × 17 × 53; 24 × 5 × 7 × 53 × 229) = 2 × 5 × 53



Divide the numerator and the denominator by their GCF:

- (2 × 5 × 132 × 17 × 53) / (24 × 5 × 7 × 53 × 229) =


- ((2 × 5 × 132 × 17 × 53) ÷ (2 × 5 × 53)) / ((24 × 5 × 7 × 53 × 229) ÷ (2 × 5 × 53)) =


- (2 ÷ 2 × 5 ÷ 5 × 132 × 17 × 53 ÷ 53)/(24 ÷ 2 × 5 ÷ 5 × 7 × 53 ÷ 53 × 229) =


- (1 × 1 × 132 × 17 × 1)/(2(4 - 1) × 1 × 7 × 1 × 229) =


- (1 × 1 × 132 × 17 × 1)/(23 × 1 × 7 × 1 × 229) =


- (132 × 17)/(23 × 7 × 229) =


- (169 × 17)/(8 × 7 × 229) =


- 2,873/12,824

Rewrite the fraction

As a decimal number:

Simply divide the numerator by the denominator, without a remainder, as shown below:


- 2,873/12,824 =


- 2,873 ÷ 12,824 ≈


- 0.224033063007 ≈


- 0.22

As a percentage:

  • A percentage value p% is equal to the fraction: p/100, for any decimal number p. So, we need to change the form of the number calculated above, to show a denominator of 100.
  • To do that, multiply the number by the fraction 100/100.
  • The value of the fraction 100/100 = 1, so by multiplying the number by this fraction the result is not changing, only the form.

- 0.224033063007 =


- 0.224033063007 × 100/100 =


( - 0.224033063007 × 100)/100 =


- 22.403306300686/100


- 22.403306300686% ≈


- 22.4%



The final answer:
written in three ways

As a negative proper fraction:
(the numerator < the denominator)
- 130/229 × 221/133 × 133/265 × 106/224 = - 2,873/12,824

As a decimal number:
- 130/229 × 221/133 × 133/265 × 106/224 ≈ - 0.22

As a percentage:
- 130/229 × 221/133 × 133/265 × 106/224 ≈ - 22.4%
