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.
