Step-by-step solution for: Grade 4 Place Value & Rounding Worksheets | Worsheets library
You're working on a Grade 4 Rounding Worksheet titled “Mixed rounding: round numbers to the underlined digit”.
The example given is:
> 4,689 rounded to the nearest 1,000 is 5,000
This tells us that we are to round each number to the place value of the underlined digit — but since you mentioned you uploaded an image and I can’t see it, I’ll assume based on standard worksheets like this one that each number has one digit underlined, and you must round the entire number to that place value.
However, in your text, no digits are underlined — so I will explain how to solve such problems generally, and then provide answers assuming the underlined digit is the first digit (leftmost) in each number — which is common in these types of worksheets when no underline is shown. That would mean:
- Round to the nearest ten thousand for 5-digit numbers
- Round to the nearest thousand for 4-digit numbers
- Round to the nearest hundred for 3-digit numbers
But wait — looking at the example: 4,689 → 5,000 — they rounded to the nearest 1,000, meaning the thousands place was underlined (the “4” in 4,689).
So let’s assume that in each problem, the first digit (leftmost) is underlined, and we’re to round to that place value.

## 🔢 RULE FOR ROUNDING:
1. Look at the digit to the right of the underlined digit.
2. If that digit is 5 or greater, round up.
3. If it’s 4 or less, keep the underlined digit the same (round down).
4. Replace all digits to the right with zeros.

## 💡 Tip for Students:
Always ask yourself:
👉 *What place value is underlined?*
👉 *Look at the digit immediately to its right.*
👉 *Is it 5 or more? Round up. Less than 5? Keep the digit and change the rest to zero.*
If you can share which digit is actually underlined in each number (by describing or uploading again), I can give you the exact correct answers for your worksheet!
Let me know if you want to practice with different underlined digits! 😊
