Question

What is 80.159 rounded to the nearest hundredth

Answer 1

80.160 I believe.

The hundredth in this case is the 5

So you look at the number to it's right. In this case the 9. 

If it's greater than 4 (in this case it's 9 so it is) you round up your hundredth up by one and default the number to it's right to 0.

Answer 2

When you round to the nearest hundredth, you round to two numbers after the decimal place

So the answer is 80.16
The 5 becomes a 6 because the number after it (9) is larger than 5

Hope this helps
