Answer
(a) 177.60
(b) 185.98
Work Step by Step
(a) Draw a "cut-off" line after the hundredths place: "177.60". Next, look at the first number after the cut-off line: "2". If the number is 4 or below, round down to the nearest hundredth: "177.60". Note: You are rounding to the nearest hundredth, so show the "0" in the hundredth's place (177.60, not 177.6).
(b) Draw a "cut-off" line after the hundredths place: "185.98". Next, look at the first number after the cut-off line: "1". If the number is 4 or below, round down to the nearest hundredth: "185.98".
