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: 875/1,000
- The prime factorizations of the numerator and denominator:
- 875 = 53 × 7
- 1,000 = 23 × 53
- 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 (875; 1,000) = 53 = 125
875/1,000 = (875 ÷ 125)/(1,000 ÷ 125) = 7/8
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
875/1,000 = (53 × 7)/(23 × 53) = ((53 × 7) ÷ 53)/((23 × 53) ÷ 53) = 7/8
The fraction: 7/8
7/8 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 7 is a prime number.
- 8 = 23
- GCF (7; 8) = 1
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.
