Which point on the number line has the coordinate \(\frac{\sqrt{225}-6}{9}\)?
Answer and explanation
Correct answer: \(1\)
First evaluate the square root: \(\sqrt{225}=15\). Therefore, \(\frac{\sqrt{225}-6}{9}=\frac{15-6}{9}=\frac{9}{9}=1\). Hence, the point is \(1\). Exam tip: follow the order of operations carefully; \(\frac{9}{15}\) is incorrect because it reverses the intended numerator and denominator.
