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: - 19/272
- 19/272 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 19 is a prime number.
- 272 = 24 × 17
- GCF (19; 272) = 1
The fraction: - 25/275
- The prime factorizations of the numerator and denominator:
- 25 = 52
- 275 = 52 × 11
- 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 (25; 275) = 52 = 25
- 25/275 = - (25 ÷ 25)/(275 ÷ 25) = - 1/11
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 25/275 = - 52/(52 × 11) = - (52 ÷ 52)/((52 × 11) ÷ 52) = - 1/11
