Question

A client weighed \(95 \mathrm{~kg}\) on the initial visit to the clinic. When the client reported for the subsequent visit the client reported losing \(11 \mathrm{lb}\). What is the client's current weight in kg? ______ \(\mathrm{kg}\)

Short answer

The client's current weight is approximately 90.01 kg.

Step-by-step solution

Convert Pounds to Kilograms

First, we need to convert the weight loss from pounds to kilograms. Since 1 pound is approximately equal to 0.453592 kilograms, we multiply the number of pounds by this conversion factor. So, the weight lost in kilograms is calculated as follows: Weight lost in kilograms = 11 lb × 0.453592 kg/lb. This gives us the weight loss in kilograms.

Calculate the Weight Loss in Kilograms

Now let's do the arithmetic for the conversion: Weight lost in kilograms = 11 lb × 0.453592 kg/lb = 4.989512 kg. So, the client lost approximately 4.99 kg.

Subtract the Weight Lost from the Initial Weight

Next, subtract the weight lost in kilograms from the initial weight of the client to find the current weight: Current weight in kg = Initial weight in kg - Weight lost in kg. Plug in the numbers: Current weight in kg = 95 kg - 4.99 kg = 90.01 kg.

Key concepts

Weight Conversion

Weight conversion is an important skill in handling real-world problems, especially when dealing with international units. Understanding how to convert between pounds and kilograms is vital for many practical scenarios. One pound is equivalent to approximately 0.453592 kilograms. This conversion factor allows seamless transition between these units. When converting, multiply the number of pounds by this factor to get the equivalent weight in kilograms. For instance, when someone loses 11 pounds, you multiply 11 by 0.453592.

• This helps in converting any weight from pounds to kilograms.
• It becomes essential when dealing with medical records, nutrition plans, or any global standard measures.

Arithmetic Operations

Arithmetic operations form the foundation of solving problems related to measurements and conversions. When working with weight conversions, you primarily handle multiplication and subtraction. In our problem, multiplication is used to convert pounds (11 lb) to kilograms using the conversion factor (0.453592 kg/lb). This operation results in determining the weight loss in kilograms. It is critical to perform this multiplication carefully to maintain precision, especially in professional fields like medicine and science. After obtaining the result from multiplication, subtraction is used to determine the current weight. The lost weight in kilograms (4.99 kg) is subtracted from the initial weight (95 kg). Through these operations:

• We ensure accurate adjustments to weight changes.
• We can correctly calculate remaining balances by adding or subtracting values.

Weight Calculation

Weight calculation is the final step once the necessary conversions and operations have been performed. In the case at hand, you begin with an initial weight, adjust for the lost weight, and find the current weight in kilograms. Starting at 95 kg, the client lost about 4.99 kg as calculated. You apply subtraction to determine the new weight: 95 kg - 4.99 kg, giving a current weight of 90.01 kg. This demonstrates the importance of accurately tracking weight changes, especially in healthcare or fitness contexts.

• Accurate weight measurement is crucial for monitoring health progress.
• Calculating weight changes help in setting realistic health goals and evaluating treatment effectiveness.

Taking all these steps ensures comprehensive understanding and accuracy in determining the present weight, an essential aspect of weight management. This methodical approach allows for precision and clarity in how changes in weight affect overall health assessments.
