Let’s play a game called target number. Here’s how it works: I give you a target number and starting number and you tell me what I need to get there.
For example, our target number is $0.2$0.2, and if I tell you the number $0.8$0.8 you would say $4$4, because $0.8\div4=0.2$0.8÷4=0.2.
Find the missing number below for our target number $0.1$0.1.
