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%
