A puzzling GDI+ Q...;)

[uniquegodwin]

Hello everyone...
Heres a puzzling question..
I want to draw bars across a form...and I am not able to draw all across the form..(Not doing a very serious project,just having fun doing something crazy.)

private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
		{
			
		drawbars(e.Graphics,Color.Red,Color.Blue,3,0);
			drawbars(e.Graphics,Color.Yellow,Color.Red,(this.Width/6),0);
			drawbars(e.Graphics,Color.Green,Color.Blue,(this.Width/3),0);
			drawbars(e.Graphics,Color.Chocolate,Color.White,(this.Width/2),0);
			
			
			//drawbars(e.Graphics,Color.BlueViolet,Color.Honeydew,(this.Width/-1),0);

		}
		private void drawbars(Graphics g,Color x,Color y,int i,int j)
		{

			System.Drawing.Rectangle rec=new Rectangle(i,j,(this.Width/5),(this.Height));
			LinearGradientBrush grad=new LinearGradientBrush(rec,x,y,10,true);

g.FillRectangle(grad,rec);

		}

		private void Form1_Resize(object sender, System.EventArgs e)
		{
			this.Invalidate();

		}

So,can someone help me achieve drawing bars till the right end of the form?
Thank Youuu

well just the wrong math
drawbars(e.Graphics,Color.Red,Color.Blue,3,0);
drawbars(e.Graphics,Color.Yellow,Color.Red,(this.Width/4),0);
drawbars(e.Graphics,Color.Green,Color.Blue,(this.Width/2),0);
drawbars(e.Graphics,Color.Chocolate,Color.White,(int)(this.Width *3.0/4),0);

I just changed the width * whatever's
and inside the draw function, change /5 to /4

Wow Mr Polite,You're too good at Math too...Awesomeeee

hmmm,but,this correction you made leaves a white gap between each bar.Its perfect apart from that.

I was actually trying to draw many bars all across the form..without any gaps between the bars and no empty space on the right side.I dont know what math i should use though.
Forgive me since Im bad at math.
