Worked Solution
Step 1: Write all four lengths aligned at the decimal point.
Ravi: 2.053
Priya: 2.305
Siti: 2.350
Wei Lin: 2.503
Step 2: Compare the ones digit — all are 2, so move to tenths.
Ravi: 0 | Priya: 3 | Siti: 3 | Wei Lin: 5
Wei Lin (5) > Priya and Siti (3) > Ravi (0)
Step 3: Break the tie between Priya (2.305) and Siti (2.350).
Tenths both 3 — compare hundredths: Priya 0, Siti 5.
5 > 0, so Siti (2.350) > Priya (2.305)
Step 4: Final order longest to shortest:
Wei Lin (2.503) > Siti (2.350) > Priya (2.305) > Ravi (2.053)
Correct answer: Wei Lin, Siti, Priya, Ravi
