Question

which is a rational number
17 -82 28.555... 0

Answer 1

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Let's evaluate the numbers you provided:

1. **17** - This is an integer and can be expressed as \( \frac{17}{1} \), so it is a rational number.
2. **-82** - This is also an integer and can be expressed as \( \frac{-82}{1} \), so it is a rational number.
3. **28.555...** - This is a repeating decimal, which can also be expressed as a fraction (for example, \( \frac{256}{9} \)), making it a rational number.
4. **0** - This is an integer and can be expressed as \( \frac{0}{1} \), so it is a rational number.

All four of the numbers you provided (17, -82, 28.555..., and 0) are rational numbers.
