Explanation:
To subtract -18 9/17 from -18 9/17, we can treat both values as fractions and subtract them.
First, let's convert the mixed numbers into improper fractions:
-18 9/17 is equivalent to (-18 * 17 + 9) / 17 = (-306 + 9) / 17 = -297 / 17.
Now we can subtract the two fractions:
(-297 / 17) - (-297 / 17) = -297 / 17 + 297 / 17.
Since the denominators are the same, we can add the numerators and keep the denominator:
(-297 + 297) / 17 = 0 / 17 = 0.
Therefore, -18 9/17 (-18 9/17) is equal to 0.
