8.174 rounded to nearest whole number

8

Step-by-step explanation: Look at the first digit after the decimal point, if it is less than 5 than you do not have to do anything. In this case, it is less than five so it is closer to zero, which is why we count it and all the numbers behind it like a zero. It does not work that way for some problems! Hope this helps!

1<5, 7>5, 4<5, 4 does not change the 7. 7 makes the 1 a 2.

2 still less than 5.

So, the answer is 8
