English: What is one and a half times as much as 8? Answer: 12
One and a half times as much means: you take something as a whole. You then add half of the thing to the whole. The total sum is one and a half times as much. Example: one and a half times as much as 20 means: you take the 20 and then add half of 20 (which is 10). The result then is 30.
