Answer 1

To convert kilograms to pounds, we can use the proportion 1 kilogram = 2.2 pounds.

To find how many kilograms are equal to 72 pounds, we can set up the following equation:

1 kilogram = 2.2 pounds
x kilograms = 72 pounds

To solve for x (the number of kilograms), we can cross multiply:

x = (72 pounds)(1 kilogram/2.2 pounds)
x = 32.7272727... kilograms

Rounding to the nearest tenth, we get:

x ≈ 32.7 kilograms

So, the answer is 32.7.
