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%
