Question

the number line shows an unknown number, w. is -\frac{w}{2} positive or negative? positive negative

Explanation:

Step1: Analyze the position of w

From the number - line, we can see that - 1 < w < 0, so w is negative.

Step2: Analyze the sign of -\frac{w}{2}

Since w is negative, - w is positive. And dividing a positive number (- w) by a positive number (2) gives a positive number. So -\frac{w}{2} is positive.

Answer:

positive
