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: - 10/95
- The prime factorizations of the numerator and denominator:
- 10 = 2 × 5
- 95 = 5 × 19
- 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 (10; 95) = 5
- 10/95 = - (10 ÷ 5)/(95 ÷ 5) = - 2/19
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 10/95 = - (2 × 5)/(5 × 19) = - ((2 × 5) ÷ 5)/((5 × 19) ÷ 5) = - 2/19
The fraction: - 17/102
- 17 is a prime number.
- 102 = 2 × 3 × 17
- GCF (17; 102) = 17
- 17/102 = - (17 ÷ 17)/(102 ÷ 17) = - 1/6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 17/102 = - 17/(2 × 3 × 17) = - (17 ÷ 17)/((2 × 3 × 17) ÷ 17) = - 1/6
