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: - 151/188
- 151/188 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 151 is a prime number.
- 188 = 22 × 47
- GCF (151; 188) = 1
The fraction: - 142/219
- 142/219 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 142 = 2 × 71
- 219 = 3 × 73
- GCF (142; 219) = 1
The fraction: - 129/232
- 129/232 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 129 = 3 × 43
- 232 = 23 × 29
- GCF (129; 232) = 1
The fraction: - 128/262
- The prime factorizations of the numerator and denominator:
- 128 = 27
- 262 = 2 × 131
- 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 (128; 262) = 2
- 128/262 = - (128 ÷ 2)/(262 ÷ 2) = - 64/131
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 128/262 = - 27/(2 × 131) = - (27 ÷ 2)/((2 × 131) ÷ 2) = - 64/131
The fraction: - 127/296
- 127/296 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 127 is a prime number.
- 296 = 23 × 37
- GCF (127; 296) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 151/188 ⟶ 11,241,097,152 ÷ 151 = (26 × 3 × 43 × 71 × 127 × 151) ÷ 151 = 74,444,352
- 142/219 ⟶ 11,241,097,152 ÷ 142 = (26 × 3 × 43 × 71 × 127 × 151) ÷ (2 × 71) = 79,162,656
- 129/232 ⟶ 11,241,097,152 ÷ 129 = (26 × 3 × 43 × 71 × 127 × 151) ÷ (3 × 43) = 87,140,288
- 64/131 ⟶ 11,241,097,152 ÷ 64 = (26 × 3 × 43 × 71 × 127 × 151) ÷ 26 = 175,642,143
- 127/296 ⟶ 11,241,097,152 ÷ 127 = (26 × 3 × 43 × 71 × 127 × 151) ÷ 127 = 88,512,576
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:
- 151/188 = - (74,444,352 × 151)/(74,444,352 × 188) = - 11,241,097,152/13,995,538,176
- 142/219 = - (79,162,656 × 142)/(79,162,656 × 219) = - 11,241,097,152/17,336,621,664
- 129/232 = - (87,140,288 × 129)/(87,140,288 × 232) = - 11,241,097,152/20,216,546,816
- 64/131 = - (175,642,143 × 64)/(175,642,143 × 131) = - 11,241,097,152/23,009,120,733
- 127/296 = - (88,512,576 × 127)/(88,512,576 × 296) = - 11,241,097,152/26,199,722,496
