The numerators and the denominators of the fractions are multiplied separately

These fractions reduce each other:

They have numerators and denominators of equal values.


The fractions: 66/104 × 98/66 = 98/104

Rewrite the equivalent simplified operation:

- 66/104 × 98/66 =


- 98/104

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: 98/104

The prime factorizations of the numerator and denominator:

98 = 2 × 72

104 = 23 × 13


GCF (98; 104) = 2


98/104 =

(98 ÷ 2)/(104 ÷ 2) =

49/52


Yet another method to reduce a fraction:

* To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.


98/104 =


(2 × 72)/(23 × 13) =


((2 × 72) ÷ 2)/((23 × 13) ÷ 2) =


(2 ÷ 2 × 72)/(23 ÷ 2 × 13) =


(1 × 72)/(2(3 - 1) × 13) =


(1 × 72)/(22 × 13) =


49/52



Rewrite the equivalent simplified operation:

- 98/104 =


- 49/52

Rewrite the fraction

As a decimal number:

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


- 49/52 =


- 49 ÷ 52 ≈


- 0.942307692308 ≈


- 0.94

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.

- 0.942307692308 =


- 0.942307692308 × 100/100 =


( - 0.942307692308 × 100)/100 =


- 94.230769230769/100


- 94.230769230769% ≈


- 94.23%



The final answer:
written in three ways

As a negative proper fraction:
(the numerator < the denominator)
- 66/104 × 98/66 = - 49/52

As a decimal number:
- 66/104 × 98/66 ≈ - 0.94

As a percentage:
- 66/104 × 98/66 ≈ - 94.23%
