Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
- To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
The fraction: 76/114
- The prime factorizations of the numerator and denominator:
- 76 = 22 × 19
- 114 = 2 × 3 × 19
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (76; 114) = 2 × 19 = 38
76/114 = (76 ÷ 38)/(114 ÷ 38) = 2/3
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
76/114 = (22 × 19)/(2 × 3 × 19) = ((22 × 19) ÷ (2 × 19))/((2 × 3 × 19) ÷ (2 × 19)) = 2/3
The fraction: 82/123
- 82 = 2 × 41
- 123 = 3 × 41
- GCF (82; 123) = 41
82/123 = (82 ÷ 41)/(123 ÷ 41) = 2/3
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
82/123 = (2 × 41)/(3 × 41) = ((2 × 41) ÷ 41)/((3 × 41) ÷ 41) = 2/3
The fractions are equal.
This is one of the simplest cases when comparing two fractions.
Not only are the numerators of the fractions equal but their denominators are also equal.
