Working percentage in c#

Question

I have two values one with a decimal value and another value with a value which will calculate the percentage of that decimal value for example:

60 % of 10 = 6

decimal value1 = 10;
decimal percentage = 60;
textbox1.text = ("mathsum here").toString();

How would you calculate this value using the decimal value and value containing the percentage value?

Answer 1

number * percentage / 100

so

10 * 60 / 100 = 6
