The Correct Answer and Explanation is:
Here are the correct answers for the conversions:
15 kg = 33.07 lbs
30 kg = 66.14 lbs
10 kg = 22.05 lbs
Explanation
The task requires converting a unit of mass from the metric system, kilograms (kg), to a unit from the imperial system, pounds (lbs). This is a common conversion that relies on a specific multiplication factor.
The key to solving these problems is knowing the conversion rate between kilograms and pounds. By international agreement, one kilogram is equivalent to approximately 2.20462 pounds. For most practical purposes, people often use a rounded value like 2.2, but for more precise results, the more accurate figure is used. The mathematical operation to convert from kilograms to pounds is multiplication. The formula is:
Pounds = Number of Kilograms × 2.20462
Using this formula, we can solve each problem step by step.
- Convert 15 kg to lbs:
We take the given mass in kilograms, which is 15, and multiply it by the conversion factor.
15 kg × 2.20462 = 33.0693 lbs.
For a clear and practical answer, we can round this to two decimal places, which gives us 33.07 lbs. - Convert 30 kg to lbs:
Next, we apply the same process to 30 kilograms.
30 kg × 2.20462 = 66.1386 lbs.
Rounding this to two decimal places results in 66.14 lbs. You might also notice that since 30 kg is double 15 kg, the answer in pounds is also double the first answer (33.07 × 2 = 66.14), which confirms our calculation. - Convert 10 kg to lbs:
Finally, we convert 10 kilograms.
10 kg × 2.20462 = 22.0462 lbs.
When we round this to two decimal places, we get 22.05 lbs. This result is consistent with the other answers, as 10 kg is one third of 30 kg, and 22.05 is roughly one third of 66.14.
In summary, any conversion from kilograms to pounds involves a simple multiplication with the established conversion factor.
