Analyze the fractions to be compared and ordered, by category:
positive proper fractions: 109/155, 110/183, 92/188, 101/209, 93/264
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: 109/155
109/155 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 109 is a prime number.
- 155 = 5 × 31
- GCF (109; 155) = 1
The fraction: 110/183
110/183 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 110 = 2 × 5 × 11
- 183 = 3 × 61
- GCF (110; 183) = 1
The fraction: 92/188
- The prime factorizations of the numerator and denominator:
- 92 = 22 × 23
- 188 = 22 × 47
- 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 (92; 188) = 22 = 4
92/188 = (92 ÷ 4)/(188 ÷ 4) = 23/47
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
92/188 = (22 × 23)/(22 × 47) = ((22 × 23) ÷ 22)/((22 × 47) ÷ 22) = 23/47
The fraction: 101/209
101/209 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 101 is a prime number.
- 209 = 11 × 19
- GCF (101; 209) = 1
The fraction: 93/264
- 93 = 3 × 31
- 264 = 23 × 3 × 11
- GCF (93; 264) = 3
93/264 = (93 ÷ 3)/(264 ÷ 3) = 31/88
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
93/264 = (3 × 31)/(23 × 3 × 11) = ((3 × 31) ÷ 3)/((23 × 3 × 11) ÷ 3) = 31/88
Calculate the common numerator
The common numerator is nothing else than the least common multiple (LCM) of the numerators of the fractions.
To calculate the LCM, we need the prime factorization of the numerators:
109 is a prime number.
110 = 2 × 5 × 11
23 is a prime number.
101 is a prime number.
31 is a prime number.
Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).
LCM (109, 110, 23, 101, 31) = 2 × 5 × 11 × 23 × 31 × 101 × 109 = 863,435,870
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
109/155 ⟶ 863,435,870 ÷ 109 = (2 × 5 × 11 × 23 × 31 × 101 × 109) ÷ 109 = 7,921,430
110/183 ⟶ 863,435,870 ÷ 110 = (2 × 5 × 11 × 23 × 31 × 101 × 109) ÷ (2 × 5 × 11) = 7,849,417
23/47 ⟶ 863,435,870 ÷ 23 = (2 × 5 × 11 × 23 × 31 × 101 × 109) ÷ 23 = 37,540,690
101/209 ⟶ 863,435,870 ÷ 101 = (2 × 5 × 11 × 23 × 31 × 101 × 109) ÷ 101 = 8,548,870
31/88 ⟶ 863,435,870 ÷ 31 = (2 × 5 × 11 × 23 × 31 × 101 × 109) ÷ 31 = 27,852,770
Make the numerators 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 numerator:
109/155 = (7,921,430 × 109)/(7,921,430 × 155) = 863,435,870/1,227,821,650
110/183 = (7,849,417 × 110)/(7,849,417 × 183) = 863,435,870/1,436,443,311
23/47 = (37,540,690 × 23)/(37,540,690 × 47) = 863,435,870/1,764,412,430
101/209 = (8,548,870 × 101)/(8,548,870 × 209) = 863,435,870/1,786,713,830
31/88 = (27,852,770 × 31)/(27,852,770 × 88) = 863,435,870/2,451,043,760
