The question in the image asks:

**"500 g of a stack weighs 2200 g. How many grams of the stack weigh 3.5 kg?"**

To solve this, we can use a simple proportion. Here's the breakdown:

1. We know that 500 grams of the stack weigh 2200 grams.
2. We are asked to find how many grams of the stack (let's call it \( x \)) weigh 3500 grams (since 3.5 kg = 3500 g).

We set up the proportion:

\[
\frac{500 \, \text{g}}{2200 \, \text{g}} = \frac{x}{3500 \, \text{g}}
\]

Now, we can solve for \( x \).

Let me calculate it.The answer is approximately \( 795.45 \) grams. 

So, around **795 grams of the stack** weigh 3.5 kg.

Here are five related questions for practice:
1. If 1000 grams of a stack weighs 4400 grams, how many grams weigh 5.5 kg?
2. How would the proportion change if 600 grams weighed 3000 grams?
3. If 250 grams of a stack weigh 1100 grams, what is the total weight for 4 kg?
4. Can you calculate how much 2 kg of the stack weighs, given 1 kg weighs 4400 grams?
5. What if a different material had the same weight per gram ratio—how would that impact weight calculations?

**Tip**: When setting up proportions, always keep the units consistent (grams, kilograms, etc.) for accuracy!
