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: 25/50
- The prime factorizations of the numerator and denominator:
- 25 = 52
- 50 = 2 × 52
- 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 (25; 50) = 52 = 25
25/50 = (25 ÷ 25)/(50 ÷ 25) = 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
25/50 = 52/(2 × 52) = (52 ÷ 52)/((2 × 52) ÷ 52) = 1/2
The fraction: 28/56
- 28 = 22 × 7
- 56 = 23 × 7
- GCF (28; 56) = 22 × 7 = 28
28/56 = (28 ÷ 28)/(56 ÷ 28) = 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
28/56 = (22 × 7)/(23 × 7) = ((22 × 7) ÷ (22 × 7))/((23 × 7) ÷ (22 × 7)) = 1/2
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.
