Analyze the fractions to be compared and ordered, by category:
positive proper fractions: 104/175, 103/160, 95/184, 101/229, 105/261
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: 104/175
104/175 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 104 = 23 × 13
- 175 = 52 × 7
- GCF (104; 175) = 1
The fraction: 103/160
103/160 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 103 is a prime number.
- 160 = 25 × 5
- GCF (103; 160) = 1
The fraction: 95/184
95/184 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 95 = 5 × 19
- 184 = 23 × 23
- GCF (95; 184) = 1
The fraction: 101/229
101/229 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 101 is a prime number.
- 229 is a prime number.
- GCF (101; 229) = 1
The fraction: 105/261
- The prime factorizations of the numerator and denominator:
- 105 = 3 × 5 × 7
- 261 = 32 × 29
- 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 (105; 261) = 3
105/261 = (105 ÷ 3)/(261 ÷ 3) = 35/87
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
105/261 = (3 × 5 × 7)/(32 × 29) = ((3 × 5 × 7) ÷ 3)/((32 × 29) ÷ 3) = 35/87
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:
104 = 23 × 13
103 is a prime number.
95 = 5 × 19
101 is a prime number.
35 = 5 × 7
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 (104, 103, 95, 101, 35) = 23 × 5 × 7 × 13 × 19 × 101 × 103 = 719,471,480
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
104/175 ⟶ 719,471,480 ÷ 104 = (23 × 5 × 7 × 13 × 19 × 101 × 103) ÷ (23 × 13) = 6,917,995
103/160 ⟶ 719,471,480 ÷ 103 = (23 × 5 × 7 × 13 × 19 × 101 × 103) ÷ 103 = 6,985,160
95/184 ⟶ 719,471,480 ÷ 95 = (23 × 5 × 7 × 13 × 19 × 101 × 103) ÷ (5 × 19) = 7,573,384
101/229 ⟶ 719,471,480 ÷ 101 = (23 × 5 × 7 × 13 × 19 × 101 × 103) ÷ 101 = 7,123,480
35/87 ⟶ 719,471,480 ÷ 35 = (23 × 5 × 7 × 13 × 19 × 101 × 103) ÷ (5 × 7) = 20,556,328
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:
104/175 = (6,917,995 × 104)/(6,917,995 × 175) = 719,471,480/1,210,649,125
103/160 = (6,985,160 × 103)/(6,985,160 × 160) = 719,471,480/1,117,625,600
95/184 = (7,573,384 × 95)/(7,573,384 × 184) = 719,471,480/1,393,502,656
101/229 = (7,123,480 × 101)/(7,123,480 × 229) = 719,471,480/1,631,276,920
35/87 = (20,556,328 × 35)/(20,556,328 × 87) = 719,471,480/1,788,400,536
