Worked Solution

Step 1: Write all four distances with the same number of decimal places. Ahmad: 1.25 m = 1.250 m Siti: 1.52 m = 1.520 m Ravi: 1.05 m = 1.050 m Mei Ling: 1.5 m = 1.500 m Step 2: Compare the tenths digit (first decimal place). Ravi 1.0__ → tenths = 0 ← smallest so far Ahmad 1.2__ → tenths = 2 Siti 1.5__ → tenths = 5 Mei Ling 1.5__ → tenths = 5 (tie with Siti) Step 3: For the tie (1.500 vs 1.520), compare hundredths. Mei Ling 1.50_ → hundredths = 0 Siti 1.52_ → hundredths = 2 → Siti is longer Final order (shortest → longest): 1.05 m, 1.25 m, 1.5 m, 1.52 m.

Correct answer: 1.05 m, 1.25 m, 1.5 m, 1.52 m
