Can 12 over 18 be reduced?

Answer 1

Yes, 12/18 can be reduced : (divide both by 2) it turns into 6/9 then (divide both by 3) into 2/3. Reduction is the division of both numerator and denominator by the same term (one of the 'factors', integer constituents, of both numbers). For even numbers, divide both by 2 until one or both become odd, then attempt higher numerical factors (3, 5, 7, etc.). 12 = 2x2x3 and 18 = 2x3x3 / common factors are one 2 and one 3. Dividing numerator and denominator by 6 will yield the reduced value 2/3.
