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: - 3/32
- 3/32 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 3 is a prime number.
- 32 = 25
- GCF (3; 32) = 1
The fraction: - 7/42
- The prime factorizations of the numerator and denominator:
- 7 is a prime number.
- 42 = 2 × 3 × 7
- 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 (7; 42) = 7
- 7/42 = - (7 ÷ 7)/(42 ÷ 7) = - 1/6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 7/42 = - 7/(2 × 3 × 7) = - (7 ÷ 7)/((2 × 3 × 7) ÷ 7) = - 1/6
