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.
