in order to solve this, you have to divide 156 by 12, but if you don't know how, you can just add the smaller number (12) over and over again, until you get the bigger number (156). then count how many times you added the small number, like this: 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 156. then count the number of 12s you added. and you get 13. : ) but please do note that this way of finding answers to questions like these don't work always, and could take a long time to do.
