To convert kilograms to pounds, we can use the proportion 1 kilogram = 2.2 pounds.
Therefore, 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
To solve for x (the number of kilograms), we can cross-multiply and solve for x:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
2.2x = 72
Dividing both sides by 2.2:
x = 72 / 2.2
x ≈ 32.7
Therefore, 72 pounds is equal to approximately 32.7 kilograms.
Rounding to the nearest tenth of a kilogram, the answer is: 32.7 kilograms.
So the correct answer is:
O 32.7
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you can set up a proportion and solve for the unknown variable.
The proportion can be written as:
1 kilogram / 2.2 pounds = X kilograms / 72 pounds
To solve for X, you can cross multiply and divide:
(1 kilogram) * (72 pounds) = (2.2 pounds) * (X kilograms)
72 pounds = 2.2X kilograms
Divide both sides by 2.2 to solve for X:
X = 72 pounds / 2.2
X ≈ 32.7
So, 72 pounds is approximately equal to 32.7 kilograms.
Therefore, the answer is option O: 32.7.
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you can set up a proportion and solve for the unknown value.
Let's call the unknown number of kilograms "x". The proportion can be set up as:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
To solve for x, you would cross-multiply and divide:
1 kilogram * 72 pounds = 2.2 pounds * x kilograms
72 pounds = 2.2x kilograms
Divide both sides by 2.2 to isolate x:
72 pounds / 2.2 = x kilograms
The result is approximately 32.727 kilograms.
However, since we are asked to round to the nearest tenth of a kilogram, the answer would be 32.7 kilograms.
Therefore, the correct answer is option O 32.7.
