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: 92/180 × 153/92 = 153/180
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: 153/180
The prime factorizations of the numerator and denominator:
153 = 32 × 17
180 = 22 × 32 × 5
GCF (153; 180) = 32 = 9
153/180 =
(153 ÷ 9)/(180 ÷ 9) =
17/20
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.
153/180 =
(32 × 17)/(22 × 32 × 5) =
((32 × 17) ÷ 32)/((22 × 32 × 5) ÷ 32) =
(32 ÷ 32 × 17)/(22 × 32 ÷ 32 × 5) =
(3(2 - 2) × 17)/(22 × 3(2 - 2) × 5) =
(30 × 17)/(22 × 30 × 5) =
(1 × 17)/(22 × 1 × 5) =
17/20

Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
17/20 =
17 ÷ 20 =
0.85
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.
0.85 =
0.85 × 100/100 =
(0.85 × 100)/100 =
85/100 =
85%
