What is the ascending order of (8.008), (8.0808), (8.0088), and (8.800)?
Answer and explanation
Correct answer: \(8.008<8.0088<8.0808<8.800\)
Write all numbers up to four decimal places: \(8.0080, 8.0808, 8.0088, 8.8000\). The first decimal digits are \(0,0,0,8\), so \(8.8000\) is the greatest. Among the remaining numbers, \(8.0080<8.0088<8.0808\). Hence, the ascending order is \(8.008<8.0088<8.0808<8.800\). Option D incorrectly places \(8.0808\) before \(8.0088\). Exam tip: append trailing zeros to make the decimal places equal before comparing decimals.
