The Correct Answer and Explanation is:
To convert 2.2 pounds to ounces, we use a unit multiplier based on the fact that:
1 pound = 16 ounces
Step-by-step conversion:
Multiply the number of pounds by the number of ounces per pound:2.2 pounds×16 ounces per pound=35.2 ounces2.2 \text{ pounds} \times 16 \text{ ounces per pound} = 35.2 \text{ ounces}2.2 pounds×16 ounces per pound=35.2 ounces
Now, round 35.2 to the nearest ounce:Rounded result=35 ounces\text{Rounded result} = 35 \text{ ounces}Rounded result=35 ounces
Final Answer:
35 ounces
Explanation:
To convert a weight from pounds to ounces, we need to use a unit multiplier that expresses the relationship between the two units. In this case, we are given that 1 pound equals 16 ounces. That means for every pound, there are 16 ounces. So, to find out how many ounces are in a certain number of pounds, we simply multiply the pounds by 16.
We start with 2.2 pounds. This number comes from the approximate weight of 1 kilogram on Earth since 1 kilogram is about 2.2 pounds. The goal is to convert this into ounces. So, the operation becomes:2.2×16=35.22.2 \times 16 = 35.22.2×16=35.2
The multiplication shows that 2.2 pounds is equal to 35.2 ounces. However, since the question asks us to round to the nearest ounce, we look at the decimal part, which is 0.2. Because this is less than 0.5, we round down. So 35.2 becomes 35 ounces when rounded to the nearest whole number.
This method is an example of using dimensional analysis, where we multiply a known value by a conversion factor (or unit multiplier) to switch units. We make sure the units cancel properly. Here, “pounds” cancels out, and we are left with “ounces.”
This is a practical skill often used in cooking, science, and other fields where converting between units is necessary for accuracy and consistency.
