3. Convert kilometers to meters:
   1 km = 1,000 meters, so 18 km = 18,000 meters.

4. Can 917 be evenly divided by 5?
   Answer: No. A number divisible by 5 must end in 0 or 5.

5. Addition problem: 47 + 24 = ?
   Answer: 71

6. Circle the greatest number:
   Out of 684,087,987, 646,354, and 2,657,305,003, the greatest number is 2,657,305,003.

7. Write a fraction for the number of shaded squares:
   There are 4 squares in total, and 1 square is shaded, so the fraction is 1/4.

8. Continue the number pattern: 72, 64, 56, ___, ___, ___
   The pattern decreases by 8 each time.
   Next numbers: 48, 40, 32.

9. How many tickets would $8 buy?
   The table shows that $2 buys 5 tickets, $4 buys 10 tickets, and $6 buys 15 tickets. The relationship between dollars and tickets is proportional.
   For $8:
   $\text{Tickets} = \frac{5}{2} \times 8 = 20 \, \text{tickets}$

10. How many tickets would $10 buy?
    Following the same proportion:
    $\text{Tickets} = \frac{5}{2} \times 10 = 25 \, \text{tickets}$
