If 1 kilogram is approximately 2.2 pounds, about how many kilograms are equal to 8.8 pounds?
The Correct Answer and Explanation is:
To find how many kilograms are equal to 8.8 pounds, we use the conversion factor:
1 kilogram ≈ 2.2 pounds
To convert pounds to kilograms, divide the number of pounds by the number of pounds per kilogram:Kilograms=Pounds2.2=8.82.2=4 kilograms\text{Kilograms} = \frac{\text{Pounds}}{2.2} = \frac{8.8}{2.2} = 4 \, \text{kilograms}Kilograms=2.2Pounds=2.28.8=4kilograms
✅ Correct Answer: 4 kilograms
🔍 Explanation
Converting between different units of measurement is a common task in math, science, and everyday life. In this case, we’re converting pounds (lbs) to kilograms (kg) using the known conversion factor:
1 kilogram ≈ 2.2 pounds
This means that one kilogram weighs about 2.2 pounds. So, if something weighs 2.2 pounds, it has a mass of approximately 1 kilogram. To reverse this and go from pounds to kilograms, we need to do the opposite operation of multiplication: we divide.
We’re given 8.8 pounds and asked how many kilograms this is. The formula is:Kilograms=Pounds2.2\text{Kilograms} = \frac{\text{Pounds}}{2.2}Kilograms=2.2Pounds
So we divide 8.8 by 2.2:8.8÷2.2=48.8 \div 2.2 = 48.8÷2.2=4
This tells us that 8.8 pounds is equivalent to 4 kilograms.
Let’s verify it the other way around:
If 1 kg ≈ 2.2 lbs, then 4 kg ≈ 4 × 2.2 = 8.8 lbs.
This confirms that the calculation is accurate.
This type of conversion is useful in many fields, such as travel (when checking luggage weight limits), health (when recording body weight in different countries), and science (when measuring mass). Knowing how to switch between units accurately ensures clear communication and correct measurements across different systems of measurement—especially between the metric system (used in most of the world) and the imperial system (used in the U.S.).
So, to summarize: 8.8 pounds is equal to 4 kilograms because dividing 8.8 by 2.2 gives us 4.
