Explanation:

Step1: Recall conversion factors

1 pound = 453.59237 grams.

Step2: Calculate for 10 pounds

$10\times453.59237 = 4535.9237\approx4536$ grams.

Step1: Recall conversion factor

1 short ton = 0.907185 metric tons.

Step2: Calculate for 50 short tons

$50\times0.907185 = 45.35925\approx45.36$ metric tons.

Step1: Recall conversion factor

1 kg = 2.20462 pounds.

Step2: Calculate for 180 kg

$180\times2.20462=396.8316\approx396.83$ pounds.

Step1: Recall conversion factor

1 kg = 2.20462 pounds.

Step2: Calculate for 745 kg

$745\times2.20462 = 1642.4419\approx1642.44$ pounds. But the closest option is a. 1642.42

Answer:

b. 4536
