2/5

Step-by-step explanation:

27/40 already reduced to the lowest terms;

the numerator and the denominator have no common prime factors:

27 = 3^3;

40 = 2^3 × 5

3/5 already reduced to the lowest terms;

the numerator and the denominator have no common prime factors:

3 is a prime number

5 is a prime number

5/8 already reduced to the lowest terms;

the numerator and the denominator have no common prime factors:

5 is a prime number;

8 = 2^3

6/15 = (2 × 3)/(3 × 5) = ((2 × 3) ÷ 3)/((3 × 5) ÷ 3) = 2/5.
