Rounding Rule for Two Decimal Places:

Look at the third decimal digit (6 in 3.8461).

If it is 5 or greater, round the second decimal digit up (4 → 5).

If it is less than 5, keep the second decimal digit unchanged.

Third decimal digit = 6 (≥5), so round the second decimal (4) up to 5.

Result: 3.85
