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: 36/38 × 38/56 = 36/56
Rewrite the equivalent simplified operation:
- 36/38 × 38/56 =
- 36/56
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: 36/56
The prime factorizations of the numerator and denominator:
36 = 22 × 32
56 = 23 × 7
GCF (36; 56) = 22 = 4
36/56 =
(36 ÷ 4)/(56 ÷ 4) =
9/14
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.
36/56 =
(22 × 32)/(23 × 7) =
((22 × 32) ÷ 22)/((23 × 7) ÷ 22) =
(22 ÷ 22 × 32)/(23 ÷ 22 × 7) =
(2(2 - 2) × 32)/(2(3 - 2) × 7) =
(20 × 32)/(21 × 7) =
(1 × 32)/(2 × 7) =
9/14

Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
- 9/14 =
- 9 ÷ 14 ≈
- 0.642857142857 ≈
- 0.64
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.
- 0.642857142857 =
- 0.642857142857 × 100/100 =
( - 0.642857142857 × 100)/100 =
- 64.285714285714/100 ≈
- 64.285714285714% ≈
- 64.29%
