Answer 2

Problem Statement

You have 3 identical packs of coffee with a total mass of 285 g. You need to find the mass of 6 such packs and solve the problem using 2 different methods.

Method 1: Proportional Method

To find the mass of 6 packs of coffee, we can set up a proportion using the given information.

Let's assume the mass of one pack of coffee is x g.

According to the problem, we have the following proportion:

3 packs / 285 g = 6 packs / x g

To solve for x, we can cross-multiply and solve the equation:

3 * x = 285 * 6

Simplifying the equation:

3 x = 1710

Dividing both sides by 3:

x = 570

Therefore, the mass of one pack of coffee is 570 g.

To find the mass of 6 packs, we can multiply the mass of one pack by 6:

Mass of 6 packs = 570 g * 6 = 3420 g

So, the mass of 6 packs of coffee is 3420 g.

Method 2: Addition Method

Another way to solve this problem is by using the given information directly.

We know that the total mass of 3 packs of coffee is 285 g.

To find the mass of 6 packs, we can divide the total mass by the number of packs and then multiply by the desired number of packs:

Mass of 6 packs = (285 g / 3 packs) * 6 packs

Simplifying the equation:

Mass of 6 packs = 95 g/pack * 6 packs

Mass of 6 packs = 570 g

So, the mass of 6 packs of coffee is 570 g.

Conclusion

Using both methods, we found that the mass of 6 packs of coffee is 570 g.
