Comparing Two-Digit Numbers (Greater/Less Than) — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which symbol makes this true? 82 ___ 28
A) <
B) =
C) >
D) none
82 has 8 tens and 28 has only 2 tens. Since 8 is much more than 2, the > symbol goes between them.
2. Which number is less than 45?
A) 54
B) 46
C) 45
D) 39
39 has 3 tens, which is fewer than the 4 tens in 45. That makes 39 the number less than 45.
3. Which statement is wrong?
A) 73 > 37
B) 66 = 66
C) 51 < 15
D) 88 > 78
51 has 5 tens and 15 has only 1 ten, so 51 is actually greater than 15. Saying 51 < 15 is wrong.
4. Which pair shows equal numbers?
A) 34 and 43
B) 29 and 92
C) 57 and 57
D) 61 and 16
Only 57 and 57 are the same number. Equal means both numbers must have the same tens and ones digits.
Part B: Fill in the Blank
Write the correct answer on each line.
1. 76 > 67 (>, <, or =)
76 has 7 tens and 67 has 6 tens. Since 7 tens is more than 6 tens, 76 is the greater number.
2. 43 = 43 (>, <, or =)
Both sides show 43 with the same tens and ones. When two numbers match, they are equal.
3. 25 < 52 (>, <, or =)
25 has 2 tens and 52 has 5 tens. Fewer tens means a smaller number, so 25 is less than 52.
4. 91 > 19 (>, <, or =)
91 has 9 tens while 19 has just 1 ten. The digits look reversed, but 91 is much greater than 19.
5. 38 < 83 (>, <, or =)
38 has 3 tens and 83 has 8 tens. Since 3 is less than 8, 38 is less than 83.
