Worked Solution
Step 1: Rewrite all scores with the same number of decimal places.
Ahmad: 3.080
Siti: 3.800
Priya: 3.090
Ravi: 3.008
Step 2: Compare the tenths digit first (all have 0 in tenths except Siti who has 8).
Siti (3.800) is the largest.
Step 3: Among Ahmad (3.080), Priya (3.090) and Ravi (3.008), compare hundredths digits.
Ravi: 0 in hundredths
Ahmad: 8 in hundredths
Priya: 9 in hundredths
So Ravi < Ahmad < Priya.
Step 4: Ascending order: Ravi (3.008) < Ahmad (3.080) < Priya (3.090) < Siti (3.800).
Answer: Ravi, Ahmad, Priya, Siti.
Correct answer: Ravi, Ahmad, Priya, Siti
