To Find:

The standard form / simplest form of the given fraction.

Solution:

The given problem can be solved using the concepts of prime factorization.

1. The given fraction is 12/40.

2. Factorize 12 as the product of prime numbers,

=> 12 = 2 x 6,

=> 12 = 2 x 2 x 3,

3. Factorize 40 as the product of prime factors,
