Real-world examples of rounding to the nearest hundred thousand

📚 Quick Study Guide

• 📍 Identify the Hundred Thousands Place: This is the 6th digit from the right (ones, tens, hundreds, thousands, ten thousands, hundred thousands).
• 👀 Look at the Digit to the Right: Check the ten thousands place (the digit immediately to the right of the hundred thousands place).
• ⚖️ Rounding Rule:
  • 🔢 If the digit in the ten thousands place is 5 or greater, round up the hundred thousands place.
  • 📉 If the digit in the ten thousands place is less than 5, keep the hundred thousands place the same.
• ➡️ Replace Remaining Digits: Change all digits to the right of the hundred thousands place to zeros.
• 🌍 Example: Round 1,567,890 to the nearest hundred thousand. The digit in the hundred thousands place is 5. The digit to the right (ten thousands) is 6 (which is >= 5). Round up, so 1,567,890 becomes 1,600,000.
