Asking questions also requires some prerequisites. Not having successfully graduated from elementary school is not an option, sorry.

Please don't be angry with me

No, I'm not angry at all, why? hope you won't be angry, too. You need to learn by yourself and rely on yourself more.
Thank you for understanding.

I'm a beginner and no one taught me how to use VB and VB.net. I learn by my self with help of files on vb.net and the rest I found on the internet. so some of the thing that stack me up, I have to ask for help.

## Solution 1

Divide the number by 100.

This answer has been accepted? I'm with SA.

## Solution 2

Just parse the number in the textbox to a double and divide it by 100:
VB
```Dim value As String = textBox1.Text
Dim num As Double
If Double.TryParse(value, num) Then
Dim percentage As Double = num / 100
textBox2.Text = percentage.ToString()
Else
' cannot parse the given string to a double
End If```
