Answer 1

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.
