Final answer:
The absolute value of 3/9 is 1/3, since the fraction simplifies to 1/3 and the absolute value of a positive number is the number itself.
Step-by-step explanation:
The absolute value of a number is its distance from zero on the number line, regardless of direction.
In other words, it's always a positive number or zero. When dealing with the absolute value of a fraction like 3/9, you first simplify the fraction if possible, and then take the absolute value.
In this case, the fraction 3/9 can be simplified to 1/3, since both the numerator (3) and the denominator (9) are divisible by 3. The absolute value of 1/3 is simply 1/3 because it is already a positive number.
Therefore, the absolute value of 3/9 is 1/3.
