Answer 2

Step-by-step explanation:

GCD Method :

step 1 Address the formula, input parameters & values.

Input parameters & values:

The given fraction = 21/27

step 2 Find GCD (Greatest Common Factor) for both numerator & denominator.

The GCF for 21 & 27 is 3

step 3 divide the numerator & denominator by GCD 3 and rewrite the fraction

= (21/3) / (27/3)

= 7/9

Thus, 7/9 is the simplified fraction for 21/27 by using the GCD or HCF method.

Prime Factorization Method :

step 1 Address input parameters & values.

Input parameters & values:

The given fraction = 21/27

step 2 Find prime factors for both numerator & denominator and rewrite the fraction in the form of prime factors

Prime factors for 21 = 3 x 7

Prime factors for 27 = 3 x 3 x 3

= (3 x 7) / (3 x 3 x 3)

step 3 solve & rewrite the fraction

= ( 7)/( 3 x 3)

= 7/9

Thus, 7/9 is the simplified fraction for 21/27 by using the prime factorization method
