Analyze the fractions to be compared and ordered, by category:
positive proper fractions: 189/270, 164/263, 160/289, 159/336, 181/375
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: 189/270
- The prime factorizations of the numerator and denominator:
- 189 = 33 × 7
- 270 = 2 × 33 × 5
- 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 (189; 270) = 33 = 27
189/270 = (189 ÷ 27)/(270 ÷ 27) = 7/10
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
189/270 = (33 × 7)/(2 × 33 × 5) = ((33 × 7) ÷ 33)/((2 × 33 × 5) ÷ 33) = 7/10
The fraction: 164/263
164/263 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 164 = 22 × 41
- 263 is a prime number.
- GCF (164; 263) = 1
The fraction: 160/289
160/289 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 160 = 25 × 5
- 289 = 172
- GCF (160; 289) = 1
The fraction: 159/336
- 159 = 3 × 53
- 336 = 24 × 3 × 7
- GCF (159; 336) = 3
159/336 = (159 ÷ 3)/(336 ÷ 3) = 53/112
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
159/336 = (3 × 53)/(24 × 3 × 7) = ((3 × 53) ÷ 3)/((24 × 3 × 7) ÷ 3) = 53/112
The fraction: 181/375
181/375 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 181 is a prime number.
- 375 = 3 × 53
- GCF (181; 375) = 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:
7 is a prime number.
164 = 22 × 41
160 = 25 × 5
53 is a prime number.
181 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 (7, 164, 160, 53, 181) = 25 × 5 × 7 × 41 × 53 × 181 = 440,510,560
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
7/10 ⟶ 440,510,560 ÷ 7 = (25 × 5 × 7 × 41 × 53 × 181) ÷ 7 = 62,930,080
164/263 ⟶ 440,510,560 ÷ 164 = (25 × 5 × 7 × 41 × 53 × 181) ÷ (22 × 41) = 2,686,040
160/289 ⟶ 440,510,560 ÷ 160 = (25 × 5 × 7 × 41 × 53 × 181) ÷ (25 × 5) = 2,753,191
53/112 ⟶ 440,510,560 ÷ 53 = (25 × 5 × 7 × 41 × 53 × 181) ÷ 53 = 8,311,520
181/375 ⟶ 440,510,560 ÷ 181 = (25 × 5 × 7 × 41 × 53 × 181) ÷ 181 = 2,433,760
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:
7/10 = (62,930,080 × 7)/(62,930,080 × 10) = 440,510,560/629,300,800
164/263 = (2,686,040 × 164)/(2,686,040 × 263) = 440,510,560/706,428,520
160/289 = (2,753,191 × 160)/(2,753,191 × 289) = 440,510,560/795,672,199
53/112 = (8,311,520 × 53)/(8,311,520 × 112) = 440,510,560/930,890,240
181/375 = (2,433,760 × 181)/(2,433,760 × 375) = 440,510,560/912,660,000
