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: 1/2
1/2 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 1 cannot be factored into other prime factors.
- 2 is a prime number.
- GCF (1; 2) = 1
The fraction: 2/4
- The prime factorizations of the numerator and denominator:
- 2 is a prime number.
- 4 = 22
- 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 (2; 4) = 2
2/4 = (2 ÷ 2)/(4 ÷ 2) = 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
2/4 = 2/22 = (2 ÷ 2)/(22 ÷ 2) = 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.
