Complete the multiplication wheels. The center number is multiplied by each number on the outer ring. The product should be written in the spaces between the rings.

The task is to complete multiplication wheels. The center number is multiplied by each number on the outer ring, and the product is written in the spaces between the rings.

Analysis of the image reveals three such wheels:

• Wheel 1: Center number is 4.
  Calculations:
  4 * 1 = 4
  4 * 2 = 8
  4 * 3 = 12
  4 * 4 = 16
  4 * 5 = 20
  4 * 6 = 24
  4 * 7 = 28
  4 * 8 = 32
  4 * 9 = 36
  4 * 10 = 40
• Wheel 2: Center number is 5.
  Calculations:
  5 * 1 = 5
  5 * 2 = 10
  5 * 3 = 15
  5 * 4 = 20
  5 * 5 = 25
  5 * 6 = 30
  5 * 7 = 35
  5 * 8 = 40
  5 * 9 = 45
  5 * 10 = 50
• Wheel 3: Center number is 6.
  Calculations:
  6 * 1 = 6
  6 * 2 = 12
  6 * 3 = 18
  6 * 4 = 24
  6 * 5 = 30
  6 * 6 = 36
  6 * 7 = 42
  6 * 8 = 48
  6 * 9 = 54
  6 * 10 = 60

The provided image shows the wheels with numbers but without the filled-in products. The above calculations represent the completed solutions for each wheel.
