3 divided by 2 can be expressed as the fraction 3/2.
To explain further, when you divide 3 by 2, you are essentially asking how many times 2 goes into 3. Since 2 goes into 3 one time completely, with a remainder of 1, it can be represented as a mixed number: 1 1/2. However, as an improper fraction, it remains 3/2. This means you have 3 parts, and each part is of size 1/2.
