Multiplying the common ordinary fractions: - 25/47 × - 47/27 = ? The multiplication process explained. The result written: As a positive proper fraction (the numerator < the denominator). As a decimal number. As a percentage
- 25/47 × - 47/27 = ?
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
- 25/47 × - 47/27 =

These fractions reduce each other:
They have numerators and denominators of equal values.
The fractions: 25/47 × 47/27 = 25/27
Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
To fully reduce a fraction, to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF.
* By reducing the values of the numerators and the denominators of the fractions the calculations are easier to make.
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.
* In order to easily reduce a fraction, factor its numerator and denominator. This way all the common prime factors are easily identified and crossed out, without calculating the GCF.
25/27 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
25 = 52
27 = 33
Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
25/27 =
25 ÷ 27 ≈
0.925925925926 ≈
0.93
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.
0.925925925926 =
0.925925925926 × 100/100 =
(0.925925925926 × 100)/100 =
92.592592592593/100 ≈
92.592592592593% ≈
92.59%
The final answer:
written in three ways
As a positive proper fraction:
(the numerator < the denominator)
- 25/47 × - 47/27 = 25/27
As a decimal number:
- 25/47 × - 47/27 ≈ 0.93
As a percentage:
- 25/47 × - 47/27 ≈ 92.59%
