Is 3−2 a rational number? If so, how do you write it in a form conforming to the definition of a rational number (that is, the denominator as a positive integer)?
3−2 is not a rational number because in a rational number, denominator is always a positive integer and numerator can both be negative or positive.
So, to make the fraction 3−2 a rational number, simply multiply the numerator and denominator by −1 as shown below:
3×−1−2×−1=−32
Hence, −32 is a rational number.
