Correct Answer: 78.07 kilograms
Explanation
To convert pounds to kilograms, you use the standard conversion factor:
1 pound = 0.4536 kilograms
This means that for every pound, there are 0.4536 kilograms. So, to convert 172 pounds to kilograms, we multiply:172×0.4536=78.0672172 \times 0.4536 = 78.0672172×0.4536=78.0672
Rounding to two decimal places, the result becomes:78.07 kilograms\boxed{78.07\ \text{kilograms}}78.07 kilograms
Now, let’s examine the other options provided:
- 780.07: This number is way too large and might result from a misplaced decimal or an error in the conversion factor. It suggests multiplying by something like 4.536 instead of 0.4536.
- 7.81: This number is far too small and could result from misplacing the decimal in the conversion factor or dividing instead of multiplying.
- 678: Again, this is incorrect and significantly too large, possibly a result of multiplying by 3.94 (172 × 3.94 = 678.68), which isn’t a valid conversion factor.
Why Conversion Accuracy Matters
Accurate conversions are essential, especially in fields like medicine, science, and engineering. For instance, if a medication dose is calculated based on weight, converting pounds to kilograms incorrectly can lead to a dangerous underdose or overdose.
In day-to-day life, knowing this conversion helps with interpreting weights when traveling between countries that use different systems—like the United States (pounds) and most of the rest of the world (kilograms).
Final Answer:
172 pounds=78.07 kilograms\boxed{172\ \text{pounds} = 78.07\ \text{kilograms}}172 pounds=78.07 kilograms
This is the only accurate answer based on the correct conversion factor.
