To convert kilograms to pounds, we can use the proportion 1 kilogram = 2.2 pounds.
To find out how many kilograms are equal to 72 pounds, we can set up the following equation:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
By cross-multiplying, we get:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
Simplifying:
2.2x = 72
Now, we can solve for x by dividing both sides of the equation by 2.2:
x = 72 / 2.2
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms. Hence, the correct answer is 32.7.
