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: 92/90
- The prime factorizations of the numerator and denominator:
- 92 = 22 × 23
- 90 = 2 × 32 × 5
- 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 (92; 90) = 2
92/90 = (92 ÷ 2)/(90 ÷ 2) = 46/45
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
92/90 = (22 × 23)/(2 × 32 × 5) = ((22 × 23) ÷ 2)/((2 × 32 × 5) ÷ 2) = 46/45
The fraction: 96/96
96/96 = (96 ÷ 96)/(96 ÷ 96) = 1/1 = 1
