Step-by-step solution for: Rounding Fun in the Sun - ArgoPrep
Let's solve the rounding problem step by step. The task is to round each number to the nearest ten, nearest hundred, and nearest thousand.
We'll go through each row one by one, using standard rounding rules:
- To the nearest ten: Look at the ones digit. If it’s 5 or more, round up; otherwise, round down.
- To the nearest hundred: Look at the tens digit. If it’s 5 or more, round up; otherwise, round down.
- To the nearest thousand: Look at the hundreds digit. If it’s 5 or more, round up; otherwise, round down.
---
- Nearest ten: Look at the ones digit (8). Since 8 ≥ 5, round up → 67,460
- Nearest hundred: Look at the tens digit (5). Since 5 ≥ 5, round up → 67,500
- Nearest thousand: Look at the hundreds digit (4). Since 4 < 5, round down → 67,000
But the table already shows:
- To nearest ten: 67,460 ✔
- To nearest hundred: 67,500 ✔
- To nearest thousand: 68,000 ✘ (Incorrect!)
Wait! Let's check:
67,458 → hundreds digit is 4 (from 458), so we round down to 67,000, not 68,000.
So, correct answer for nearest thousand is 67,000, not 68,000.
But the table says 68,000 — that’s a mistake.
Let’s keep going with the rest and correct as needed.
---
- Nearest ten: Ones digit = 5 → round up → 88,910 ✔ (already given)
- Nearest hundred: Tens digit = 0 → less than 5 → round down → 88,900
- Nearest thousand: Hundreds digit = 9 → ≥5 → round up → 89,000
So:
- To nearest hundred: 88,900
- To nearest thousand: 89,000
---
- Nearest ten: Ones digit = 6 → round up → 21,180
- Nearest hundred: Tens digit = 7 → ≥5 → round up → 21,200 ✔ (given)
- Nearest thousand: Hundreds digit = 1 → <5 → round down → 21,000
So:
- To nearest ten: 21,180
- To nearest thousand: 21,000
---
- Nearest ten: Ones digit = 4 → <5 → round down → 39,260
- Nearest hundred: Tens digit = 6 → ≥5 → round up → 39,300
- Nearest thousand: Hundreds digit = 2 → <5 → round down → 39,000 ✔ (given)
So:
- To nearest ten: 39,260
- To nearest hundred: 39,300
---
- Nearest ten: Ones digit = 3 → <5 → round down → 40,620
- Nearest hundred: Tens digit = 2 → <5 → round down → 40,600
- Nearest thousand: Hundreds digit = 6 → ≥5 → round up → 41,000
So:
- To nearest ten: 40,620
- To nearest hundred: 40,600
- To nearest thousand: 41,000
---
- Nearest ten: Ones digit = 1 → <5 → round down → 19,380
- Nearest hundred: Tens digit = 8 → ≥5 → round up → 19,400
- Nearest thousand: Hundreds digit = 3 → <5 → round down → 19,000
So:
- To nearest ten: 19,380
- To nearest hundred: 19,400
- To nearest thousand: 19,000
