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: 88/110
- The prime factorizations of the numerator and denominator:
- 88 = 23 × 11
- 110 = 2 × 5 × 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; 110) = 2 × 11 = 22
88/110 = (88 ÷ 22)/(110 ÷ 22) = 4/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
88/110 = (23 × 11)/(2 × 5 × 11) = ((23 × 11) ÷ (2 × 11))/((2 × 5 × 11) ÷ (2 × 11)) = 4/5
The fraction: 92/115
- 92 = 22 × 23
- 115 = 5 × 23
- GCF (92; 115) = 23
92/115 = (92 ÷ 23)/(115 ÷ 23) = 4/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
92/115 = (22 × 23)/(5 × 23) = ((22 × 23) ÷ 23)/((5 × 23) ÷ 23) = 4/5
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.
