38/71 × 71/32 = ? Multiply the Common (Ordinary) Fractions, Online Calculator. Multiplication Operation Explained Step by Step
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: 38/71 × 71/32 = 38/32
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: 38/32
The prime factorizations of the numerator and denominator:
38 = 2 × 19
32 = 25
GCF (38; 32) = 2
38/32 =
(38 ÷ 2)/(32 ÷ 2) =
19/16
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.
38/32 =
(2 × 19)/25 =
((2 × 19) ÷ 2)/(25 ÷ 2) =
(2 ÷ 2 × 19)/(25 ÷ 2) =
(1 × 19)/2(5 - 1) =
(1 × 19)/24 =
19/16

Rewrite the fraction
As a mixed number (also called a mixed fraction):
- A mixed number: a whole number and a proper fraction, both having the same sign.
- A proper fraction: the value of the numerator is smaller than the value of the denominator.
- Divide the numerator by the denominator and write down the quotient and the remainder of the division, as shown below:
19 ÷ 16 = 1 and the remainder = 3 ⇒
19 = 1 × 16 + 3 ⇒
19/16 =
(1 × 16 + 3)/16 =
(1 × 16)/16 + 3/16 =
1 + 3/16 =
1 3/16
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1 + 3/16 =
1 + 3 ÷ 16 =
1.1875 ≈
1.19
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.
1.1875 =
1.1875 × 100/100 =
(1.1875 × 100)/100 =
118.75/100 =
118.75%

The final answer:
written in four ways
As a positive improper fraction:
(the numerator >= the denominator)
38/71 × 71/32 = 19/16
As a mixed number (also called a mixed fraction):
38/71 × 71/32 = 1 3/16
As a decimal number:
38/71 × 71/32 ≈ 1.19
As a percentage:
38/71 × 71/32 = 118.75%
