1. The problem asks to arrange the numbers 0.05, 0.04, 0.045, and 0.054 from smallest to largest. 2. To compare decimal numbers, look at the digits from left to right starting from the decimal point. 3. Compare the numbers: - 0.04 has digits 0.040 (adding a zero for clarity) - 0.045 - 0.05 is 0.050 - 0.054 4. Order them by comparing each digit: - 0.04 (0.040) is smallest - 0.045 is next - 0.05 (0.050) follows - 0.054 is largest 5. So the correct order from smallest to largest is: $$0.04, 0.045, 0.05, 0.054$$ 6. This corresponds to option D. Final answer: D. 0.04, 0.045, 0.05, 0.054
