3 decimal places would be where the 9 is, since the next number is 8 , the 9 would become a 0 and the number before it (5) would become a 6

 so it would be 977.260
Rounded to 3 decimal places is 977.260. You get this by going to the third place out and looking to the right of it. if it's 5 or more round up. If your number is a nine then it becomes a 10 and youd carry it over
