To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, divide the number of pounds by 2.2.
To find out how many kilograms are equal to 72 pounds, divide 72 by 2.2.
72 / 2.2 = 32.72727272727273
Rounded to the nearest tenth, 32.7 kilograms are equal to 72 pounds.
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.
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you need to set up a proportion and solve for the unknown value.
Let x be the number of kilograms equal to 72 pounds.
Applying the proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross-multiplying, we get:
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
Simplifying, we have:
2.2x = 72
To solve for x, divide both sides of the equation by 2.2:
2.2x / 2.2 = 72 / 2.2
x = 72 / 2.2
Evaluating this expression, you find that x is approximately 32.7. Therefore, 72 pounds is equal to 32.7 kilograms (rounded to the nearest tenth of a kilogram).
