8.957 rounded to the nearest tenth is simple; it becomes 9, because you cannot round the .9 to something larger, and the .05 after it helps you figure out the tenth you need to solve (To figure out tenths, look at the hundredth. Ex: 6.78 would be rounded to 6.8, because the 8 is closer to 10, then 4 or 2 would be.) And if you were to round .9 to .0, it just wouldn't work out.
To dumb it down:
8.957 = 9
