Test questions: rounding decimals to the nearest whole number 4th grade

📚 Quick Study Guide

🔢 Identify the place value you're rounding to: Look at the digit to the right of the place value you are rounding to. 📌 Rounding Rules:
👉
• If the digit to the right is 0, 1, 2, 3, or 4, keep the digit in the rounding place the same. All digits to the right become zero.
👉
• If the digit to the right is 5, 6, 7, 8, or 9, increase the digit in the rounding place by one. All digits to the right become zero.
💡 Rounding to the Nearest Whole Number: The whole number place is to the left of the decimal point. The tenths place (the first digit after the decimal point) determines how we round. 🧮 Example: Round 3.6 to the nearest whole number. The digit in the tenths place is 6, which is 5 or greater, so we round up to 4.
