The image contains five math problems focusing on the Least Common Multiple (LCM or "KPK" in Indonesian). Here is the breakdown of the questions from the image:

1. **Surya and Tegar's Kite-Flying Schedules**  
   - Surya flies his kite every 10 days.  
   - Tegar flies his kite every 15 days.  
   - If they start flying their kites together on March 1st, when will they fly kites together again?

2. **Leon and Arga's Trampoline Training Schedules**  
   - Leon trains every 3 days.  
   - Arga trains every 2 days.  
   - If they train together on a Tuesday, on what day will they train together again?

3. **Doni and Sinta Running Schedules**  
   - Doni runs every 8 minutes.  
   - Sinta runs every 12 minutes.  
   - If they start running together at 07:00, when will they meet again at the starting point?

4. **Two Lamps with Different Intervals**  
   - One lamp blinks every 5 seconds.  
   - Another lamp blinks every 7 seconds.  
   - If both lamps blink together at 09:00, when will they blink together again?

5. **Andi and Budi's Swimming Practice**  
   - Andi swims every 9 days.  
   - Budi swims every 12 days.  
   - If they start swimming together on April 14th, when will they swim together again for the second time?

Would you like detailed solutions for each of these problems? 

Here are 5 questions to expand on this:

1. How do you calculate the Least Common Multiple (LCM) for two numbers?
2. What is the connection between LCM and finding when events will occur together again?
3. How can you find the LCM of more than two numbers?
4. What are some real-life applications of LCM apart from scheduling events?
5. How do the concepts of GCD (Greatest Common Divisor) and LCM relate?

**Tip:** To solve such problems, always break down the problem by identifying the frequency of events and finding the LCM of the given intervals.

Solve five problems involving the Least Common Multiple (LCM), focusing on schedules and recurring events.

This set of math problems focuses on calculating the Least Common Multiple (LCM) of time intervals to determine when recurring events will occur together again. Topics covered include kite flying, trampoline practice, running, blinking lights, and swimming schedules.
