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: 47/93
47/93 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 47 is a prime number.
- 93 = 3 × 31
- GCF (47; 93) = 1
The fraction: 49/98
- The prime factorizations of the numerator and denominator:
- 49 = 72
- 98 = 2 × 72
- 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 (49; 98) = 72 = 49
49/98 = (49 ÷ 49)/(98 ÷ 49) = 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
49/98 = 72/(2 × 72) = (72 ÷ 72)/((2 × 72) ÷ 72) = 1/2
