Answers

Answer:

Step-by-step explanation:

3/8

Final answer:

Among 3/8 and 2/8, the fraction 3/8 is greater because 3 is a larger number than 2. The part '312-6512' doesn't seem relevant to the problem, so it's likely a typo.

Here, 3 is bigger than 2. Thus, 3/8 is the larger fraction compared to 2/8.

Answers

Answer:

$2,424.80

Step-by-step explanation
