Analyze the fractions to be compared and ordered, by category:
positive proper fractions: 97/144, 110/161, 113/143, 103/149
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: 97/144
97/144 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 97 is a prime number.
- 144 = 24 × 32
- GCF (97; 144) = 1
The fraction: 110/161
110/161 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 110 = 2 × 5 × 11
- 161 = 7 × 23
- GCF (110; 161) = 1
The fraction: 113/143
113/143 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 113 is a prime number.
- 143 = 11 × 13
- GCF (113; 143) = 1
The fraction: 103/149
103/149 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 103 is a prime number.
- 149 is a prime number.
- GCF (103; 149) = 1
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:
97 is a prime number.
110 = 2 × 5 × 11
113 is a prime number.
103 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 (97, 110, 113, 103) = 2 × 5 × 11 × 97 × 103 × 113 = 124,188,130
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
97/144 ⟶ 124,188,130 ÷ 97 = (2 × 5 × 11 × 97 × 103 × 113) ÷ 97 = 1,280,290
110/161 ⟶ 124,188,130 ÷ 110 = (2 × 5 × 11 × 97 × 103 × 113) ÷ (2 × 5 × 11) = 1,128,983
113/143 ⟶ 124,188,130 ÷ 113 = (2 × 5 × 11 × 97 × 103 × 113) ÷ 113 = 1,099,010
103/149 ⟶ 124,188,130 ÷ 103 = (2 × 5 × 11 × 97 × 103 × 113) ÷ 103 = 1,205,710
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:
97/144 = (1,280,290 × 97)/(1,280,290 × 144) = 124,188,130/184,361,760
110/161 = (1,128,983 × 110)/(1,128,983 × 161) = 124,188,130/181,766,263
113/143 = (1,099,010 × 113)/(1,099,010 × 143) = 124,188,130/157,158,430
103/149 = (1,205,710 × 103)/(1,205,710 × 149) = 124,188,130/179,650,790
