Answer 1

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.
