you are diluting it 12/2.5 times, or 4.8 times, which means you add to one part of concentrate acid, 3.8 part water.
so what is one part? 200m/4.8= 41.67 ml.
So add 41.67ml of the 12 M HCl to 150 ml water, while steering wearing googles, then when cool, and the rest of the water up to 200ml of solution. put it in a suitable decanter, label it properly.
