Which of the following comparisons is NOT true?
(A) 42.300=42342.300 = 423
(B) 5.020<5.205.020 < 5.20
(C) 0.149<1.4900.149 < 1.490
(D) 108.308>108.4108.308 > 108.4

Ava chose (C) as the correct answer. How did she get that answer?

Step 1: Analyze option (A)

Compare 42.30042.300 and 423423.
42.30042.300 is equal to 42.342.3, which is not equal to 423423.
Thus, 42.30042342.300 \neq 423, and option (A) is NOT true.

Step 2: Analyze option (B)

Compare 5.0205.020 and 5.205.20.
5.0205.020 is equal to 5.025.02, and 5.205.20 is equal to 5.25.2.
Since 5.02<5.25.02 < 5.2, option (B) is true.

Step 3: Analyze option (C)

Compare 0.1490.149 and 1.4901.490.
0.1490.149 is less than 1.4901.490, so 0.149<1.4900.149 < 1.490 is true.
Thus, option (C) is true.

Step 4: Analyze option (D)

Compare 108.308108.308 and 108.4108.4.
108.308108.308 is less than 108.4108.4, so 108.308>108.4108.308 > 108.4 is NOT true.
Thus, option (D) is NOT true.

Step 5: Determine Ava's reasoning

Ava chose (C) as the correct answer, but (C) is actually true.
This suggests Ava made a mistake in her reasoning.
The correct answer should be either (A) or (D), as both are NOT true.

The correct answer is (A) or (D)\boxed{\text{(A) or (D)}}. Ava likely made an error in identifying the incorrect comparison.

The correct answer is (A) or (D)\boxed{\text{(A) or (D)}}. Ava likely made an error in identifying the incorrect comparison.
