Round this number to a. the nearest hundred. b. the nearest thousand. c. the nearest ten thousand SOLUTION a. Step 1. 405,648 Underline the 6 (the hundreds place). (continued) Answers to PROBLEMS 5. indd 17 6. a. \$1,013,100 b. \$1,013,000 c. 1,010,000 12/11/07 9:59:23 AM 18 Chapter 1 1-18 Whole Numbers Step 2. 405,648 Four is less than 5. Leave the 6 as is.

Our estimate (6300) is close to the answer (6346). EXAMPLE 7 PROBLEM 7 Adding whole numbers Add 5471 ϩ 2842. Add 3943 ϩ 4672. SOLUTION 11 54 7 1 ϩ2842 8 3 13 Step 1. To the nearest thousand, the estimate is 5000 ϩ 3000 ϭ 8000. Step 2. Arrange in columns. Step 3. Add ones. Step 4. Add tens. Remember to carry 1: (7 ϩ 4 ϭ 11) Step 5. Add hundreds. Remember to carry 1: (1 ϩ 4 ϩ 8 ϭ 13) Step 6. Add thousands. Note that our estimate (8000) is close to the actual answer (8313). Sometimes it is necessary to add more than two numbers.

Round this number to a. the nearest hundred. b. the nearest thousand. c. the nearest ten thousand SOLUTION a. Step 1. 405,648 Underline the 6 (the hundreds place). (continued) Answers to PROBLEMS 5. indd 17 6. a. \$1,013,100 b. \$1,013,000 c. 1,010,000 12/11/07 9:59:23 AM 18 Chapter 1 1-18 Whole Numbers Step 2. 405,648 Four is less than 5. Leave the 6 as is. Step 3. 405,6 00 ︸ Change to zeros. Thus, 405,648 rounded to the nearest hundred is 405,600. b. Step 1. 405,648 Underline the 5 (the thousands place).
