As 9 is in the ones position and under 50, we round down to zero.
Look at the digit in the ones position. That is the 9. A 9 will round the number up, so 89 will round up to 90.
You look at the digit after the last 9, which is an 8. It will round up the 9, which in turn will round up the 6. That will give 69.70 as the answer.
Assuming it is $8.98 then it will round up to $9 as there is a 9 in the tenths position after the decimal point.
Note that:9 is in the first decimal placeNext to that is another 9.Since "another" 9 is at least 5, round up the value to obtain 3.0.
