Round 6.2134618797 to the nearest millionth.
The correct answer and explanation is:
To round 6.2134618797 to the nearest millionth, first identify the digit in the millionth place. The millionth place is the sixth digit to the right of the decimal point.
The number in question is 6.2134618797.
- The digit in the millionth place is 9 (the sixth digit after the decimal point).
- The next digit after the millionth place is 7.
The rounding rule is:
- If the digit following the place you are rounding to is 5 or higher, increase the digit in the target place by 1.
- If the digit following the place you are rounding to is less than 5, leave the target digit unchanged and drop the remaining digits.
In this case, the digit after the millionth place is 7, which is greater than 5. Therefore, you increase the digit in the millionth place by 1.
So, the millionth place (9) becomes 10, but since the next place is a digit 7, this causes the rounding to carry over. The number rounded to the nearest millionth becomes 6.213462.
Thus, 6.2134618797 rounded to the nearest millionth is 6.213462.
