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: 130/24
- The prime factorizations of the numerator and denominator:
- 130 = 2 × 5 × 13
- 24 = 23 × 3
- 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 (130; 24) = 2
130/24 = (130 ÷ 2)/(24 ÷ 2) = 65/12
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
130/24 = (2 × 5 × 13)/(23 × 3) = ((2 × 5 × 13) ÷ 2)/((23 × 3) ÷ 2) = 65/12
The fraction: 136/34
- 136 = 23 × 17
- 34 = 2 × 17
- GCF (136; 34) = 2 × 17 = 34
136/34 = (136 ÷ 34)/(34 ÷ 34) = 4/1 = 4
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
136/34 = (23 × 17)/(2 × 17) = ((23 × 17) ÷ (2 × 17))/((2 × 17) ÷ (2 × 17)) = 4/1 = 4
