#### Work Step by Step

RECALL: (1) To round-off a number, check the digit immediately to the right of the round-off place. If the digit is 5 or higher, round up the value, otherwise, retain the value. Examples: Round-off to two decimal places: $23.546 \longrightarrow 23.55 \\23.544 \longrightarrow 23.54$ (2) To truncate a number, drop all digits to the right of the specific truncation place. Examples: Truncate to two decimal places: $23.546 \longrightarrow 23.54 \\23.544 \longrightarrow 23.54$ Thus, for the given number: (a) Rounded-off to three decimal places: $0.05\underline{3}\color{red}88 \longrightarrow 0.054$ (b) Truncated to three decimal places: $0.05\underline{3}\color{red}{88} \longrightarrow 0.053$
