What Does 'Least to Greatest' Mean for Three-Digit Numbers?

📚 Quick Study Guide

• 🔢 When arranging numbers from least to greatest, we start with the smallest number and end with the largest number.
• 🔍 Compare the hundreds digits first. If they are different, the number with the smaller hundreds digit is smaller.
• ⚖️ If the hundreds digits are the same, compare the tens digits. The number with the smaller tens digit is smaller.
• 📍 If the hundreds and tens digits are the same, compare the ones digits. The number with the smaller ones digit is smaller.
• 📝 Example: To order 325, 289, and 301 from least to greatest:
  • 289 has the smallest hundreds digit (2), so it's the smallest.
  • 325 and 301 both have 3 as the hundreds digit, so we compare the tens digits.
  • 301 has 0 in the tens place, and 325 has 2 in the tens place, so 301 is smaller than 325.
  • Therefore, the order is 289, 301, 325.
