Step-by-step explanation:

See the steps below, one ratio - one pair of numbers changes at a time.

      spiders    webs      days

• 8                24        6              
• 8                 4         1               ⇒   Divide by 6
• 2                 1         1               ⇒   Divide by 4
• 12                6         1               ⇒   Multiply by 6
• 12               18        3               ⇒   Multiply by 3
