Answer 1

To convert pounds to kilograms, we need to use the proportion 1 kilogram = 2.2 pounds.

Let's set up a proportion using this relationship:

1 kilogram / 2.2 pounds = x kilograms / 72 pounds.

Cross-multiplying, we have:

2.2pounds * x kilograms = 1kilogram * 72pounds.

Simplifying:

2.2x = 72.

Now, divide both sides of the equation by 2.2 to solve for x:

x = 72 / 2.2 = 32.7273 kilograms.

Rounded to the nearest tenth of a kilogram, 32.7 kilograms is equal to 72 pounds.
