step 1 Address the formula, input parameters & values. Input parameters & values: The given fraction = 220/224 step 2 Find GCD (Greatest Common Factor) for both numerator & denominator. The GCF for 220 & 224 is 4 step 3 divide the numerator & denominator by GCD 4 and rewrite the fraction = (220/4) / (224/4) = 55/56 Thus, 55/56 is the simplified fraction for 220/224 by using the GCD or HCF method. Prime Factorization Method : step 1 Address input parameters & values. Input parameters & values: The given fraction = 220/224 step 2 Find prime factors for both numerator & denominator and rewrite the fraction in the form of prime factors Prime factors for 220 = 2 x 2 x 5 x 11 Prime factors for 224 = 2 x 2 x 2 x 2 x 2 x 7 = (2 x 2 x 5 x 11) / (2 x 2 x 2 x 2 x 2 x 7) step 3 solve & rewrite the fraction = ( 5 x 11)/( 2 x 2 x 2 x 7) = 55/56 Thus, 55/56 is the simplified fraction for 220/224 by using the prime factorization method. Chart User may refer the below chart for simplest form of 220/224 and its nearest values. Fraction Reduced Form Decimal Value 216 220 54 55 0.9818 220 224 55 56 0.9821
