Hello! I am a new coder, so this is a simple question. But I am trying to create a code where you enter a number, then another number, and it divides then multiply the numbers. I put both numbers as a string, and as result when i tried to multiply/divide the numbers that were entered, an error occurred. How can i fix this? using System;

namespace Percentage_of_a_number
{
class Program
{
static object Main(string[] args)
{
Console. WriteLine("Enter percentage here");
string Percentage = Console. ReadLine();

Console. WriteLine("Enter your number here");
string Number = Console. ReadLine();

String Result = Percentage / 100 * Number;

}
}
}
