What would 12.47 rounded to 2 sig figs be?

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.  12.47

Now you want to look at the number after the underlined (I bolded that number). 12.47

If the number is above 5 then you would round the previous number up by one but in this case it is 4 so you do not increase the number. Hence, you getting 12 as your final answer.
