Chapter 4 - Decimals - 4.2 Rounding Decimal Numbers - 4.2 Exercises: 41

Answer

It becomes $0.00. The number after the cut-off line is "4", so you round down to the nearest ones. If the number is 4 or below, round down to the nearest ones: "0.0".

Work Step by Step

When you round to the nearest dollar, you are rounding to the nearest ones. Draw a "cut-off" line after the ones place: "0". Next, look at the first number after the cut-off line: "4". If the number is 4 or below, round down to the nearest ones: "0.0".
