This exercise asks you to round each number to the nearest ten. The rule for rounding to the nearest ten is: If the ones digit is 5 or greater (5, 6, 7, 8, 9), round up to the next multiple of ten. If the ones digit is less than 5 (0, 1, 2, 3, 4), round down to the current multiple of ten. Step 1: Solve Problem 11. The number is 9114. The ones digit is 4. Since 4 is less than 5, round down. 9114 → 9110 Step 2: Solve Problem 12. The number is 423. The ones digit is 3. Since 3 is less than 5, round down. 423 → 420 Step 3: Solve Problem 13. The number is 567. The ones digit is 7. Since 7 is 5 or greater, round up. 567 → 570 Step 4: Solve Problem 14. The number is 666. The ones digit is 6. Since 6 is 5 or greater, round up. 666 → 670 Step 5: Solve Problem 15. The number is 789. The ones digit is 9. Since 9 is 5 or greater, round up. 789 → 790 Step 6: Solve Problem 16. The number is 142. The ones digit is 2. Since 2 is less than 5, round down. 142 → 140 Step 7: Solve Problem 17. The number is 719. The ones digit is 9. Since 9 is 5 or greater, round up. 719 → 720 Step 8: Solve Problem 18. The number is 222. The ones digit is 2. Since 2 is less than 5, round down. 222 → 220 Step 9: Solve Problem 19. The number is 286. The ones digit is 6. Since 6 is 5 or greater, round up. 286 → 290 Step 10: Solve Problem 20. The number is 620. The ones digit is 0. Since 0 is less than 5, round down (it's already a multiple of ten). 620 → 620 That's 2 down. 3 left today — send the next one.
