To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you need to divide the weight in pounds by 2.2. To find out how many kilograms are equal to 72 pounds, you would use the following calculation:
72 pounds ÷ 2.2 = 32.7 kilograms (rounded to the nearest tenth of a kilogram)
So, 72 pounds is equal to approximately 32.7 kilograms.
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you can set up a proportion equation and solve for the unknown value.
Let x be the number of kilograms equal to 72 pounds.
Therefore, the proportion would be:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
To solve this proportion, you can cross-multiply:
1 kilogram * 72 pounds = 2.2 pounds * x kilograms
72 pounds = 2.2x kilograms
Now, isolate x by dividing both sides of the equation by 2.2:
72 pounds / 2.2 = x kilograms
x ≈ 32.72727...
Finally, round x to the nearest tenth of a kilogram, which becomes:
x ≈ 32.7 kilograms
So, 72 pounds is approximately equal to 32.7 kilograms.
