Which expression has the same value as - 18-(-9)?

Option D:

–8 ÷ (–4) is equivalent to –18 ÷ (–9).

Solution:

Given expression:

–18 ÷ (–9)

Let us first solve this expression.

                 = 2  (negative by negative is positive)

To find which expression has the same value for the given expression:

Option A: –18 ÷ 2

             = –9 (negative by positive is negative)

This is not equivalent expression.

Option B: –12 ÷ (–3)

                 = 4  (negative by negative is positive)

This is not equivalent expression.

Option C: –10 ÷ 5

             = –2 (negative by positive is negative)

This is not equivalent expression.

Option D: –8 ÷ (–4)

                 = 2  (negative by negative is positive)

This is the equivalent expression to the given expression.

Hence –8 ÷ (–4) is equivalent to –18 ÷ (–9).
