To write the fraction 3/6 in its simplest form, you need to reduce it by finding the greatest common divisor (GCD) of the numerator and the denominator.
The numerator is 3, and the denominator is 6. The GCD of 3 and 6 is 3.
Next, divide both the numerator and the denominator by the GCD, which is 3.
3 ÷ 3 = 1
6 ÷ 3 = 2
So, the simplified form of the fraction 3/6 is 1/2. This means that 3/6 in its simplest form is 1/2.
