Chapter 4 - Decimals - 4.2 Rounding Decimal Numbers - 4.2 Exercises: 11

Answer

3.661

Work Step by Step

We are asked to round 3.66062 to the nearest thousandth. Step 1. Draw a cut-off line after the thousandths place. We are cutting off the 6 and 2. They will be dropped. Step 2. We look at the first digit after the cut-off line, which is 6. Step 3. Since this number is greater than or equal to 5, we round up the digit in the thousandths place by 1 to 1. Therefore, 3.66062 rounded to the nearest thousandth is 3.661.
