which number line model represents the expression 3\frac{1}{2}+(-6)?
choose 1 answer:

Explanation:

Step1: Understand adding a negative number

Adding a negative number is the same as subtracting a positive number. So \(3\frac{1}{2}+(- 6)=3\frac{1}{2}-6\).

Step2: Analyze number - line representation

We start at the point \(3\frac{1}{2}\) on the number - line. Since we are subtracting 6 (or adding - 6), we move 6 units to the left.

Step3: Check the options

Option A moves to the right which is for adding a positive number. Option B starts at \(3\frac{1}{2}\) and moves 6 units to the left. Option C has incorrect starting and moving directions.

Answer:

B.
