arrange these numbers in ascending order: 2.5, 0.25, 0.025, 25, 250; options: 2.5, 0.025, 0.25, 25, 250; 0.025, 2.5, 0.25, 25, 250; 0.25, 0.025, 2.5, 25, 250; 0.025, 0.25, 2.5, 25, 250

Explanation:

Step1: Compare decimal parts

0.025 (25 thousandths), 0.25 (25 hundredths = 250 thousandths), 2.5 (25 tenths = 2500 thousandths), 25 (25000 thousandths), 250 (250000 thousandths).

Step2: Order from smallest to largest

0.025 < 0.25 < 2.5 < 25 < 250.

Answer:

0.025, 0.25, 2.5, 25, 250 (the fourth option, or the rightmost option)
