These fractions reduce each other:
They have numerators and denominators of equal values.
The fractions: 26/38 × 38/90 = 26/90
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.
26/90 =
(2 × 13)/(2 × 32 × 5) =
((2 × 13) ÷ 2)/((2 × 32 × 5) ÷ 2) =
(2 ÷ 2 × 13)/(2 ÷ 2 × 32 × 5) =
(1 × 13)/(1 × 32 × 5) =
13/45
Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
13/45 =
13 ÷ 45 ≈
0.288888888889 ≈
0.29
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.
0.288888888889 =
0.288888888889 × 100/100 =
(0.288888888889 × 100)/100 =
28.888888888889/100 ≈
28.888888888889% ≈
28.89%
The final answer:
written in three ways
As a positive proper fraction:
(the numerator < the denominator)
- 26/38 × - 38/90 = 13/45
As a decimal number:
- 26/38 × - 38/90 ≈ 0.29
As a percentage:
- 26/38 × - 38/90 ≈ 28.89%
