To convert kilograms to pounds, you can use the proportion 1 kilogram = 2.2 pounds.
Let x be the number of kilograms equal to 72 pounds.
Setting up the proportion: 1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiplying, we get 1 kilogram * 72 pounds = 2.2 pounds * x kilograms
Simplifying, we have 72 = 2.2x
Dividing both sides by 2.2, we get x = 72 / 2.2
Calculating, x ≈ 32.73
So the number of kilograms equal to 72 pounds is approximately 32.73.
Therefore, the answer is A. 32.73
