What is the ascending order of (6.006), (6.0606), (6.0066), and (6.600)?
Answer and explanation
Correct answer: \(6.006<6.0066<6.0606<6.600\)
Write all the numbers up to four decimal places: \(6.0060, 6.0066, 6.0606, 6.6000\). Thus, \(6.0060<6.0066<6.0606<6.6000\), so option A is correct. In option D, \(6.0606\) and \(6.0066\) are placed in the wrong order: their hundredths digits are 6 and 0 respectively. Exam tip: Add trailing zeros when needed to make the decimal places equal before comparing decimals.
