Decimals

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.

$0.5\div\editable{}=0.1$0.5÷=0.1
