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=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 (A) or (D). Ava likely made an error in identifying the incorrect comparison.
The correct answer is (A) or (D). Ava likely made an error in identifying the incorrect comparison.
