Dividing Speed on Robot Drive

[DavisC]

I am trying to divide the speed of the motors...
by 1/2 when Button 1 of Stick 1 is pressed;
by 3/4 when Button 1 of Stick 2 is pressed; and
by 1/4 when Button 1 of Both sticks are pressed.

Where is the best place to add the divide function.

			// Drive
			if(J_stick1.GetRawButton(1) == true)
				R_myRobot.TankDrive(J_stick1, J_stick2);
			else
				if(J_stick2.GetRawButton(1) == true)	
					R_myRobot.TankDrive(J_stick1, J_stick2)*3/4;
				else
					if(J_stick1.GetRawButton(1) == true && J_stick2.GetRawButton(2) == true)
						R_myRobot.TankDrive(J_stick1, J_stick2)/4;
					else	
						R_myRobot.TankDrive(J_stick1, J_stick2);
