134.9
-
130
-
135
Correct Answer
A. 130Explanation
When rounding a number to the nearest ten, we look at the digit in the ones place. If it is 0, 1, 2, 3, or 4, we round down to the previous ten. If it is 5, 6, 7, 8, or 9, we round up to the next ten. In this case, the digit in the ones place is 9, which is greater than 5, so we round up. Therefore, 134.9 rounded to tens will give us 140. However, none of the given options is 140. Therefore, the correct answer is 130, which is the previous ten.Rate this question:
