12
Explanation:
To get to this answer you have to look at the number first. So the given number is 12.47 and you need 2 sig figs.
To help you understand this more start off by underlining the first 2 numbers because 2 sig figs are needed. <u>12</u>.47
Now you want to look at the number after the underlined (I bolded that number). <u>12</u>.47
