Answer:
1.0
Explanation:
0.989 broken down to place values:
0 (ones)
.
9 (tenths)
8 (hundredths)
9 (thousandths)
In this case, you rounded 0.989 to 0.99. By the looks of it, you rounded to the hundredths place, which is correct. The thousandths place value was a 9, and as 9 is greater than 5, you round up.
0.989 rounded to the nearest hundredths is 0.99.
If you are rounding to the tenths, note that the tenths place value is a 9. Look at the hundredths value. It is an 8. Because 8 is greater than 5, round up.
0.989 rounded to the nearest tenths is 1.0
Why?
You are rounding to the nearest tenths. As 8 is greater than 5, you round up, adding 1 to the tenths place value.
0.9 + 0.1 = 1.0
Therefore, your answer is 1.0
