To convert pounds to kilograms, you need to divide the number of pounds by the conversion factor 2.2.
So, to convert 72 pounds to kilograms:
72 pounds / 2.2 pounds/kilogram = 32.7272727 kilograms
Rounding to the nearest tenth of a kilogram, the value is approximately 32.7 kilograms.
Therefore, the correct answer is:
O 327
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 proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiplying, we get:
72 pounds * 1 kilogram = 2.2 pounds * x kilograms
Simplifying, we have:
72 / 2.2 = x
x ≈ 32.7
Rounding to the nearest tenth of a kilogram, we get:
x ≈ 32.7 kilograms
Therefore, the answer is O 32.7.
To convert kilograms to pounds using the given proportion 1 kilogram = 2.2 pounds, you can set up a proportion and cross multiply:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiplying gives us:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
2.2x = 72
To solve for x (the number of kilograms), divide both sides of the equation by 2.2:
x = 72 / 2.2
Using a calculator, we find that x is approximately 32.73.
The question asks for the answer rounded to the nearest tenth of a kilogram. Rounding 32.73 to the nearest tenth gives us 32.7.
Therefore, 72 pounds is equal to approximately 32.7 kilograms (rounded to the nearest tenth of a kilogram).
The correct answer to this question is 32.7.
