Which statement is correct about (22/7)?
Answer and explanation
Correct answer: It is an approximation of π
\(22/7\) is the ratio of two integers with a non-zero denominator, so it is a rational number. Its value is very close to π, but it is not exactly equal to π. Therefore, option A is correct; option B is wrong because \(22/7\) is rational, and option D is wrong because \(22/7 = 3\frac{1}{7}\), which is not an integer. Exam tip: Before calling a fraction an integer, check whether its numerator is exactly divisible by its denominator.
