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: - 6/10
- The prime factorizations of the numerator and denominator:
- 6 = 2 × 3
- 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 (6; 10) = 2
- 6/10 = - (6 ÷ 2)/(10 ÷ 2) = - 3/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 6/10 = - (2 × 3)/(2 × 5) = - ((2 × 3) ÷ 2)/((2 × 5) ÷ 2) = - 3/5
The fraction: - 9/15
- 9 = 32
- 15 = 3 × 5
- GCF (9; 15) = 3
- 9/15 = - (9 ÷ 3)/(15 ÷ 3) = - 3/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 9/15 = - 32/(3 × 5) = - (32 ÷ 3)/((3 × 5) ÷ 3) = - 3/5
The fractions are equal.
This is one of the simplest cases when comparing two fractions.
Not only are the numerators of the fractions equal but their denominators are also equal.
