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

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

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

Step 1: Analyze option (A)

Compare $42.300$ and $423$.
$42.300$ is equal to $42.3$, which is not equal to $423$.
Thus, $42.300 \neq 423$, and option (A) is NOT true.

Step 2: Analyze option (B)

Compare $5.020$ and $5.20$.
$5.020$ is equal to $5.02$, and $5.20$ is equal to $5.2$.
Since $5.02 < 5.2$, option (B) is true.

Step 3: Analyze option (C)

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

Step 4: Analyze option (D)

Compare $108.308$ and $108.4$.
$108.308$ is less than $108.4$, so $108.308 > 108.4$ 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 $\boxed{\text{(A) or (D)}}$. Ava likely made an error in identifying the incorrect comparison.
