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: 88/99
- The prime factorizations of the numerator and denominator:
- 88 = 23 × 11
- 99 = 32 × 11
- 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 (88; 99) = 11
88/99 = (88 ÷ 11)/(99 ÷ 11) = 8/9
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
88/99 = (23 × 11)/(32 × 11) = ((23 × 11) ÷ 11)/((32 × 11) ÷ 11) = 8/9
The fraction: 96/108
- 96 = 25 × 3
- 108 = 22 × 33
- GCF (96; 108) = 22 × 3 = 12
96/108 = (96 ÷ 12)/(108 ÷ 12) = 8/9
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
96/108 = (25 × 3)/(22 × 33) = ((25 × 3) ÷ (22 × 3))/((22 × 33) ÷ (22 × 3)) = 8/9
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.
