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: 14/10
- The prime factorizations of the numerator and denominator:
- 14 = 2 × 7
- 10 = 2 × 5
- 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 (14; 10) = 2
14/10 = (14 ÷ 2)/(10 ÷ 2) = 7/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
14/10 = (2 × 7)/(2 × 5) = ((2 × 7) ÷ 2)/((2 × 5) ÷ 2) = 7/5
The fraction: 19/19
19/19 = (19 ÷ 19)/(19 ÷ 19) = 1/1 = 1
