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: 470/658
- The prime factorizations of the numerator and denominator:
- 470 = 2 × 5 × 47
- 658 = 2 × 7 × 47
- 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 (470; 658) = 2 × 47 = 94
470/658 = (470 ÷ 94)/(658 ÷ 94) = 5/7
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
470/658 = (2 × 5 × 47)/(2 × 7 × 47) = ((2 × 5 × 47) ÷ (2 × 47))/((2 × 7 × 47) ÷ (2 × 47)) = 5/7
The fraction: 475/665
- 475 = 52 × 19
- 665 = 5 × 7 × 19
- GCF (475; 665) = 5 × 19 = 95
475/665 = (475 ÷ 95)/(665 ÷ 95) = 5/7
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
475/665 = (52 × 19)/(5 × 7 × 19) = ((52 × 19) ÷ (5 × 19))/((5 × 7 × 19) ÷ (5 × 19)) = 5/7
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.
