Chapter 4 - Decimals - 4.2 Rounding Decimal Numbers - 4.2 Exercises: 38

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".
