Question 9

Question. 9

On the number line, the value of \((-3)\times 3\) lies on right hand side of

(a)

–10

(b)

–4

(c)

(d)

Step 1: Multiply the numbers

((-3) imes 3)

A negative number multiplied by a positive number is negative.

(3 imes 3 = 9)

So the value is:

((-3) imes 3 = -9)

Step 2: Place it on the number line

On a number line, numbers increase to the right.

(ldots,-11,,-10,,-9,,-8,ldots)

Step 3: Compare with the options

Is (-9) to the right of (-10)? Yes, because:

(-9 > -10)

Is (-9) to the right of (-4)? No, because:

(-9 < -4)

It is also not to the right of (0) or (9).

Answer: Right of (-10) (option a).
