My Empty School Bag Weighs 1 Kg 325g. I Put 2 Kg And 450g Of Books In It How Much Does The Bag Weigh Now ?
Understanding the Problem
To solve this problem, we need to understand the concept of weight and how to add weights together. Weight is a measure of the force exerted on an object due to gravity. In this case, we are dealing with kilograms and grams, which are units of mass.
Converting Weights to a Common Unit
Before we can add the weights together, we need to convert them to a common unit. Since we are dealing with kilograms and grams, we can convert everything to grams. There are 1000 grams in 1 kilogram, so:
- 1 kg 325g = 1325g
- 2 kg 450g = 2450g
Adding the Weights Together
Now that we have both weights in grams, we can add them together to find the total weight of the bag and its contents.
1325g (empty bag) + 2450g (books) = 3775g
Converting the Total Weight Back to Kilograms and Grams
Since we are used to thinking in kilograms and grams, we can convert the total weight back to this format.
3775g = 3 kg 775g
Conclusion
Therefore, the bag and its contents now weigh 3 kg 775g.
Real-World Applications
This problem may seem simple, but it has real-world applications in many areas, such as:
