I'm not sure if I completely understand your question, but from my interpretation, the answer is 170.

Explanation:

Your number is 169.948.

Whole numbers are to the left of the decimal (169).

Look at the FIRST NUMBER to the right of the decimal (9 in the .948).

Rounding Rules:

  • Less than 5 -> ROUND DOWN
  • Greater or equal to 5 -> ROUND UP

Since 9 is larger than 5, you have to round the 9 in 169 UP.

However, the next number after 9 is 10.

This means you must round the 6 in 169 UP to 7 and put a 0 instead of the 9..

You should get 170 as your answer.

This makes sense because 170 is after 169.
