Answer 1

To convert pounds to kilograms using the proportion 1 kilogram = 2.2 pounds, we can set up the following equation:

1 kilogram / 2.2 pounds = x kilograms / 72 pounds

To solve for x, we can cross multiply:

2.2 pounds * x kilograms = 1 kilogram * 72 pounds

Multiplying both sides of the equation, we get:

2.2x = 72

Dividing both sides of the equation by 2.2, we get:

x = 72 / 2.2 ≈ 32.7

Therefore, 72 pounds is approximately equal to 32.7 kilograms.
