Question

which sentence is true?
44.30 ≥ 0.23
471.934 < 0.1
0.8 > 84.9
4,184.96 < 4,184.19

Explanation:

Step1: Analyze \( 44.30 \geq 0.23 \)

Compare the two numbers. \( 44.30 \) is a positive number greater than \( 0 \), and \( 44.30 \) is much larger than \( 0.23 \). So \( 44.30 \geq 0.23 \) is true. But we need to check other options too.

Step2: Analyze \( 4721.934 < 0.1 \)

\( 4721.934 \) is a large positive number, and \( 0.1 \) is a small positive number. Clearly, \( 4721.934 > 0.1 \), so this is false.

Step3: Analyze \( 0.8 > 84.9 \)

\( 0.8 \) is less than \( 1 \), and \( 84.9 \) is greater than \( 80 \). So \( 0.8 < 84.9 \), this is false.

Step4: Analyze \( 4,184.96 < 4,184.19 \)

Compare the decimal parts. The whole number parts are the same. The decimal part of \( 4,184.96 \) is \( 0.96 \) and for \( 4,184.19 \) is \( 0.19 \). Since \( 0.96 > 0.19 \), \( 4,184.96 > 4,184.19 \), so this is false.

Answer:

\( 44.30 \geq 0.23 \) (the true sentence)
