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: 110/67
110/67 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 110 = 2 × 5 × 11
- 67 is a prime number.
- GCF (110; 67) = 1
The fraction: 109/55
109/55 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 109 is a prime number.
- 55 = 5 × 11
- GCF (109; 55) = 1
The fraction: 123/67
123/67 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 123 = 3 × 41
- 67 is a prime number.
- GCF (123; 67) = 1
The fraction: 111/64
111/64 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 111 = 3 × 37

The fraction: 392/72
- The prime factorizations of the numerator and denominator:
- 392 = 23 × 72
- 72 = 23 × 32
- 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 (392; 72) = 23 = 8
392/72 = (392 ÷ 8)/(72 ÷ 8) = 49/9
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
392/72 = (23 × 72)/(23 × 32) = ((23 × 72) ÷ 23)/((23 × 32) ÷ 23) = 49/9

Make the denominators of the fractions the same:
- Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
- This way all the fractions will have the same denominator:
