To convert kilograms to pounds, we use the proportion given: 1 kilogram = 2.2 pounds.
To find how many kilograms are equal to 72 pounds, we set up a proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds.
Cross-multiplying, we get:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds.
Simplifying:
2.2x = 72.
Dividing both sides of the equation by 2.2:
x = 72 / 2.2 ≈ 32.73.
Therefore, approximately 32.73 kilograms are equal to 72 pounds.
