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? 57 ___ 75
A) <
B) >
C) =
D) none
57 has 5 tens and 75 has 7 tens. Since 5 is less than 7, the < symbol goes between them.
2. Which number is greater than 68?
A) 59
B) 68
C) 42
D) 71
71 has 7 tens, which is more than the 6 tens in 68. That makes 71 greater than 68.
3. Which statement is correct?
A) 45 > 54
B) 32 < 23
C) 89 > 79
D) 61 = 16
89 and 79 both have 9 ones, but 89 has 8 tens while 79 has 7 tens. So 89 > 79 is true.
4. Which number is less than 50?
A) 55
B) 60
C) 47
D) 51
47 has 4 tens, which is fewer than the 5 tens in 50. So 47 is less than 50.
Part B: Fill in the Blank
Write the correct answer on each line.
1. 84 > 48 (>, <, or =)
84 has 8 tens while 48 has only 4 tens. More tens means a bigger number, so 84 is greater.
2. 36 < 63 (>, <, or =)
36 has 3 tens and 63 has 6 tens. Since 3 tens is less than 6 tens, 36 is the smaller number.
3. 99 = 99 (>, <, or =)
Both numbers are 99 with 9 tens and 9 ones on each side. They are exactly equal.
4. 17 < 71 (>, <, or =)
17 has just 1 ten, but 71 has 7 tens. Even though the digits look reversed, 17 is much less than 71.
5. 53 > 35 (>, <, or =)
53 has 5 tens and 35 has 3 tens. Since 5 tens beats 3 tens, 53 is the greater number.
