Comparing Three-Digit Numbers — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 456 < 459
6 ones is less than 9 ones, so 456 is smaller than 459.
2. 782 < 785
2 ones is less than 5 ones, so 782 < 785.
3. 634 = 634
All three place values are the same, so the numbers are equal.
4. 918 > 913
8 ones is more than 3 ones, so 918 is greater than 913.
5. 325 = 325
Hundreds, tens, and ones all match, so 325 = 325.
6. 247 > 241
7 ones is more than 1 one, so 247 is greater than 241.
7. 569 > 562
9 ones beats 2 ones, so 569 > 562.
8. 803 < 808
3 ones is less than 8 ones, so 803 is smaller than 808.
9. 175 = 175
All three digits match exactly, so 175 equals 175.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
456 vs 459
→ 456 < 459
456 < 459
634 vs 634
→ 634 = 634
634 = 634
918 vs 913
→ 918 > 913
918 > 913
782 vs 785
→ 782 < 785
782 < 785
When hundreds and tens match, the ones place alone decides the comparison.
