How to display a decimal point answer in c#

I want to equate 24/5 in my console and display the equation and answer on screen (answer = 4.8), I have written my code as: 

int answer = 24 / 5; //declare answer
Console.WriteLine("24 / 5 = " + answer);
Console.ReadLine();

I have tried using the variables decimal, double, float and int for answer but the console will always write the answer "4" and not "4.8".

Can anyone help please?

When you write 24 / 5, in this case the / operator is the operator defined for the int type (because both sides are of int type) and so the result is an int too. Try this:

double  answer = 24 / 5.0;
Console.WriteLine("24 / 5 = " + answer);

When you provide one of the operands with a double type, in this case the double form of the / operator will be used and the result will be a double too.

int answer = 24 / 5;

Everything above is int, how do you expect to get a decimal point ? even if you change the type of answer to double this would not solve the problem since 24 / 5 still returns an integer value.

To get a double value, atleast one of the operand should be of double type. Like:

double answer = (double) 24 / 5;

Or

double answer =  24d / 5;

Or 

double answer = 24.0 / 5;

Or

double answer = 24 * (1.0) / 5;

Or modify/cast 5 to double.
