Answer 1

To convert kilograms to pounds using the given proportion, we can set up the equation:

1 kilogram = 2.2 pounds

Now, we can solve for x (the number of kilograms equal to 72 pounds):

x kilograms = 72 pounds

Using the proportion, we can set up the ratio equation:

1 kilogram / 2.2 pounds = x kilograms / 72 pounds

Cross-multiplying, we get:

2.2 pounds * x kilograms = 1 kilogram * 72 pounds

2.2x = 72

Simplifying, we get:

x = 72 / 2.2

x ≈ 32.7

Therefore, 72 pounds is equal to approximately 32.7 kilograms.
