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: - 28/24
- The prime factorizations of the numerator and denominator:
- 28 = 22 × 7
- 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 (28; 24) = 22 = 4
- 28/24 = - (28 ÷ 4)/(24 ÷ 4) = - 7/6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 28/24 = - (22 × 7)/(23 × 3) = - ((22 × 7) ÷ 22)/((23 × 3) ÷ 22) = - 7/6
The fraction: - 35/30
- 35 = 5 × 7
- 30 = 2 × 3 × 5
- GCF (35; 30) = 5
- 35/30 = - (35 ÷ 5)/(30 ÷ 5) = - 7/6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 35/30 = - (5 × 7)/(2 × 3 × 5) = - ((5 × 7) ÷ 5)/((2 × 3 × 5) ÷ 5) = - 7/6
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.
