Question

lowest fraction of 243/405​

Answer 1

First we have to find the GCD of numerator and denominator:-   (GCD =  greatest common divisor )

GCD of 243 and 405 :-    

243 = 3 × 3 × 3 × 3 × 3  ( the prime factorization of 243)

405 = 3 × 3 × 3 × 3 × 5 ( the prime factorization of 405)

To find the GCD, multiply all the prime factors common to both numbers:

Therefore, GCD = 3 × 3 × 3 × 3

GCD = 81

∴ GCD of 243 and 405 is 81

Divide both the numerator and denominator by the GCD

⇒(243 ÷ 81) ÷(405 ÷ 81)

Reduced fraction: $\frac{3}{5}$

Hence,$\frac{243}{405}$ simplified to lowest terms is $\frac{3}{5}$

Ans:- The lowest fraction of 243/405​ will be ( $\frac{3}{5}$ ).
