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.
