positive proper fractions: 125/186, 119/182, 111/209, 112/233, 114/297
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: 125/186
125/186 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 125 = 53
- 186 = 2 × 3 × 31
- GCF (125; 186) = 1
The fraction: 119/182
- The prime factorizations of the numerator and denominator:
- 119 = 7 × 17
- 182 = 2 × 7 × 13
- 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 (119; 182) = 7
119/182 = (119 ÷ 7)/(182 ÷ 7) = 17/26
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
119/182 = (7 × 17)/(2 × 7 × 13) = ((7 × 17) ÷ 7)/((2 × 7 × 13) ÷ 7) = 17/26
The fraction: 111/209
111/209 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 111 = 3 × 37
- 209 = 11 × 19
- GCF (111; 209) = 1
The fraction: 112/233
112/233 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 112 = 24 × 7
- 233 is a prime number.
- GCF (112; 233) = 1
The fraction: 114/297
- 114 = 2 × 3 × 19
- 297 = 33 × 11
- GCF (114; 297) = 3
114/297 = (114 ÷ 3)/(297 ÷ 3) = 38/99
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
114/297 = (2 × 3 × 19)/(33 × 11) = ((2 × 3 × 19) ÷ 3)/((33 × 11) ÷ 3) = 38/99
Calculate the common denominator
The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
To calculate the LCM, we need the prime factorization of the denominators:
186 = 2 × 3 × 31
26 = 2 × 13
209 = 11 × 19
233 is a prime number.
99 = 32 × 11
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 (186, 26, 209, 233, 99) = 2 × 32 × 11 × 13 × 19 × 31 × 233 = 353,248,038
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
125/186 ⟶ 353,248,038 ÷ 186 = (2 × 32 × 11 × 13 × 19 × 31 × 233) ÷ (2 × 3 × 31) = 1,899,183
17/26 ⟶ 353,248,038 ÷ 26 = (2 × 32 × 11 × 13 × 19 × 31 × 233) ÷ (2 × 13) = 13,586,463
111/209 ⟶ 353,248,038 ÷ 209 = (2 × 32 × 11 × 13 × 19 × 31 × 233) ÷ (11 × 19) = 1,690,182
112/233 ⟶ 353,248,038 ÷ 233 = (2 × 32 × 11 × 13 × 19 × 31 × 233) ÷ 233 = 1,516,086
38/99 ⟶ 353,248,038 ÷ 99 = (2 × 32 × 11 × 13 × 19 × 31 × 233) ÷ (32 × 11) = 3,568,162
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:
125/186 = (1,899,183 × 125)/(1,899,183 × 186) = 237,397,875/353,248,038
17/26 = (13,586,463 × 17)/(13,586,463 × 26) = 230,969,871/353,248,038
111/209 = (1,690,182 × 111)/(1,690,182 × 209) = 187,610,202/353,248,038
112/233 = (1,516,086 × 112)/(1,516,086 × 233) = 169,801,632/353,248,038
38/99 = (3,568,162 × 38)/(3,568,162 × 99) = 135,590,156/353,248,038
