Final answer:
The question involves simplifying the addition of two weights in different units by converting grams to kilograms and adding them together, resulting in a final weight of 9.779 kg. It emphasizes the importance of using consistent units and representing the correct number of significant figures.
Step-by-step explanation:
The student is asking how to simplify the addition of weights in kilograms and grams. The question involves adding 5 kg 595 g to 4 kg 184 g. To simplify, we first convert grams to kilograms by dividing by 1000, as there are 1000 grams in 1 kilogram. This gives us:
- 5 kg + 0.595 kg
- 4 kg + 0.184 kg
When we add these numbers together, we obtain:
5 + 0.595 + 4 + 0.184 = 9.779 kg
Therefore, the simplified weight is 9.779 kg. When expressing units, if a problem requires a specific unit like grams or kilograms, it is important to use that unit for consistency. In addition, when adding or subtracting, the final answer should have the same number of decimal places as the least-precise starting value. This is to correctly represent the significant figures in our measurements.
