Answer: 4
Step-by-step explanation: The word "of" tells us that we need to multiply so we have 1/3 x 12. Now, if a fraction doesn't have a denominator, just give it a denominator of 1 because it means the same thing.
To multiply fractions, we multiply across their numerators and multiply across their denominators so 1/3 x 12/1 is 12/3.
To reduce the fraction, divide both the top and bottom by 3 and we get 4/1 or 4.
So, 1/3 of 12 is 4.
