What type of decimal expansion will the rational number (-\frac{9}{28}) have?
Answer and explanation
Correct answer: Non-terminating recurring
Step 1: The negative sign does not change the type of decimal expansion. Step 2: (28=2^2\times7), so the factor (7) makes the decimal non-terminating recurring. Step 3: Check the denominator in lowest form, not the sign.
