To round 115 to two significant figures, you first identify the two most significant digits, which are 1 and 1. The third digit, 5, is the deciding factor for rounding. Since 5 is equal to or greater than 5, you round up the last significant digit. Therefore, 115 rounded to two significant figures is 120.
Well, honey, when you're rounding 115 to two significant figures, you gotta look at that first non-zero digit, which is 1. The second significant figure is the 1 after that, so you keep the 1 and ditch the 5. That leaves you with 120.

What are the rules in multiplication and division of significant figures?
The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.
