To convert kilograms to pounds, we use the proportion 1 kilogram = 2.2 pounds.
We can set up the following equation:
x kilograms = 72 pounds
To solve for x, we can set up the proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross-multiplying, we have:
2.2x = 72
Dividing both sides by 2.2, we get:
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms.
The correct option is 32.7.
