Answer:
351.7
Explanation:
Look at the tenths space which is one place to the right of the decimal. It is a 6.
Then look at the number behind it: if the number behind is is 4 or less the number in front stays the same, if the number behind it is 5 or more the number in front goes up one more
so there is an 8 behind the 6, so you round the 6 to a 7
