- 3/8 × - 3/8 = ? Multiply the Common (Ordinary) Fractions, Online Calculator. Multiplication Operation Explained Step by Step

Please check the entered string:
5 - The denominator of the fraction is not an integer.

3 - The denominator of the fraction is not an integer.

The numerators and the denominators of the fractions are multiplied separately

Simplify the operation

Rewrite the equivalent simplified operation:

Combine the signs of the fractions into a single one, placed in front of the expression. If the sign is + then it is usually not written.


The sign of a multiplication operation:


+ 1 × + 1 = + 1

+ 1 × - 1 = - 1

- 1 × - 1 = + 1


- 3/8 × - 3/8 =


3/8 × 3/8

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: 3/8

3/8 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors.


The prime factorizations of the numerator and denominator:

3 is a prime number (it cannot be factored into other prime factors)

8 = 23


GCF (3; 8) = 1


Perform the operation of calculating the fractions

Multiply the fractions:

Multiply the numerators, that is, all the numbers above fractions bars, separately.

Multiply the denominators, that is, all the numbers below fractions bars, separately.


3/8 × 3/8 =


(3 × 3) / (8 × 8) =


(3 × 3) / (23 × 23) =


32 / 26

Reduce (simplify) the end fraction to its lowest terms equivalent:

Calculate the greatest common factor, GCF,
of the numerator and denominator of the fraction:

  • 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).
  • But the numerator and the denominator have no common prime factors:


GCF (32; 26) = 1



Divide the numerator and the denominator by their GCF:

The numerator and the denominator of the fraction are coprime numbers (they have no common prime factors, the GCF = 1). The end fraction can no longer be reduced, it already has the smallest possible numerator and denominator.


32 / 26 =


9/64

Rewrite the fraction

As a decimal number:

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


9/64 =


9 ÷ 64 =


0.140625 ≈


0.14

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.

0.140625 =


0.140625 × 100/100 =


(0.140625 × 100)/100 =


14.0625/100 =


14.0625% ≈


14.06%



The final answer:
written in three ways

As a positive proper fraction:
(the numerator < the denominator)
- 3/8 × - 3/8 = 9/64

As a decimal number:
- 3/8 × - 3/8 ≈ 0.14

As a percentage:
- 3/8 × - 3/8 ≈ 14.06%
