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: - 128/169
- 128/169 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 128 = 27
- 169 = 132
- GCF (128; 169) = 1
The fraction: - 110/178
- The prime factorizations of the numerator and denominator:
- 110 = 2 × 5 × 11
- 178 = 2 × 89
- 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 (110; 178) = 2
- 110/178 = - (110 ÷ 2)/(178 ÷ 2) = - 55/89
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 110/178 = - (2 × 5 × 11)/(2 × 89) = - ((2 × 5 × 11) ÷ 2)/((2 × 89) ÷ 2) = - 55/89
The fraction: - 109/192
- 109/192 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 109 is a prime number.
- 192 = 26 × 3
- GCF (109; 192) = 1
The fraction: - 118/246
- 118 = 2 × 59
- 246 = 2 × 3 × 41
- GCF (118; 246) = 2
- 118/246 = - (118 ÷ 2)/(246 ÷ 2) = - 59/123
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 118/246 = - (2 × 59)/(2 × 3 × 41) = - ((2 × 59) ÷ 2)/((2 × 3 × 41) ÷ 2) = - 59/123
The fraction: - 119/275
- 119/275 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 119 = 7 × 17
- 275 = 52 × 11
- GCF (119; 275) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 128/169 ⟶ 5,387,634,560 ÷ 128 = (27 × 5 × 7 × 11 × 17 × 59 × 109) ÷ 27 = 42,090,895
- 55/89 ⟶ 5,387,634,560 ÷ 55 = (27 × 5 × 7 × 11 × 17 × 59 × 109) ÷ (5 × 11) = 97,956,992
- 109/192 ⟶ 5,387,634,560 ÷ 109 = (27 × 5 × 7 × 11 × 17 × 59 × 109) ÷ 109 = 49,427,840
- 59/123 ⟶ 5,387,634,560 ÷ 59 = (27 × 5 × 7 × 11 × 17 × 59 × 109) ÷ 59 = 91,315,840
- 119/275 ⟶ 5,387,634,560 ÷ 119 = (27 × 5 × 7 × 11 × 17 × 59 × 109) ÷ (7 × 17) = 45,274,240
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:
- 128/169 = - (42,090,895 × 128)/(42,090,895 × 169) = - 5,387,634,560/7,113,361,255
- 55/89 = - (97,956,992 × 55)/(97,956,992 × 89) = - 5,387,634,560/8,718,172,288
- 109/192 = - (49,427,840 × 109)/(49,427,840 × 192) = - 5,387,634,560/9,490,145,280
- 59/123 = - (91,315,840 × 59)/(91,315,840 × 123) = - 5,387,634,560/11,231,848,320
- 119/275 = - (45,274,240 × 119)/(45,274,240 × 275) = - 5,387,634,560/12,450,416,000
