Answer 1

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
