Final answer:
The Cub Scouts can make 20 first aid kits.
Step-by-step explanation:
To determine the number of first aid kits the Cub Scouts can make, we need to find the limiting factor between the number of band-aids and antiseptic ointment packets.
Since the goal is to make all the kits exactly the same, we need to divide the supplies evenly.
Dividing the number of band-aids by the desired number of kits will give us the number of band-aids per kit. Similarly, dividing the number of antiseptic ointment packets by the desired number of kits will give us the number of ointment packets per kit. Taking the smaller value of the two will determine the maximum number of first aid kits that can be made.
In this case, the smaller value is 20, so the Cub Scouts can make 20 first aid kits.
