To convert kilograms to pounds, we can use the proportion 1 kilogram = 2.2 pounds.
Let's set up the proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiplying, we get:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
And simplifying, we have:
2.2x = 72
Now, we can solve for x:
x = 72 / 2.2
Calculating, we find:
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms.
The correct response is: 32.7.
