To simplify the fraction 12/16, you want to find the greatest common divisor (GCD) of the numerator (12) and the denominator (16). The GCD of 12 and 16 is 4, as it is the largest number that divides both 12 and 16 without leaving a remainder.

Next, you divide both the numerator and the denominator by their GCD:

- Divide the numerator: \( 12 ÷ 4 = 3 \)

- Divide the denominator: \( 16 ÷ 4 = 4 \)

This gives you the simplified fraction \( \frac{3}{4} \).

The resulting fraction, \( \frac{3}{4} \), is in its simplest form because 3 and 4 share no common factors other than 1. So, 12/16 simplifies to 3/4 correctly.
