\( 3 \times ? \quad \) sim \( =30,000 \)

To find the missing number, we can start by setting up the equation: \( 3 \times ? = 30,000 \). To isolate the question mark, we simply divide both sides by 3. Therefore, \( ? = 30,000 \div 3 \), which gives us \( ? = 10,000 \). So the missing number is 10,000! In real-world applications, this kind of equation often appears in budgeting or inventory calculations where you might need to find out how many items or units are grouped based on a fixed number. For instance, if each pack contains 3 items and you have 30,000 items in total, you're actually dealing with 10,000 packs! How neat is that?
