Help : Find Value

[manu666]

Hello to everything, first of all my English is not very good.

I would like you to tell me how I can look for a value.

I have a game on Android where I want to unlock characters, something like this:

Character 1: 20/100
Character 2: 75/250
Character 3: 2/50

How can I do to find and convert the number 20 to 100 or the number 75 to 250.

Keep in mind that these values can not be increased since there are events in other months that cause these values to rise.

Thanks!!!!!
