To express 1.5 as a fraction, first recognize that 1.5 is equivalent to 1 and 0.5, or 1 plus one half. In fraction form, the whole number 1 can be written as 2/2, making it easier to combine both parts. Thus, 1.5 can be rewritten as:

1.5 = 1 + 0.5 = 2/2 + 1/2 = (2 + 1) / 2 = 3/2.

This shows that 1.5 is equivalent to the fraction 3/2. Notably, this conversion aligns with the understanding that 1.5 represents one whole and an additional half, clearly illustrated by this fraction.

The other options do not represent the value of 1.5 accurately. For example, 1/2 represents a fraction less than 1, while 5/4 is greater than 1. Finally, 2/3 is also a fraction less than 1, confirming that 3/2 is the correct representation of 1.5 as a fraction.
