The given value is 26.66666....
The tenth place is the first digit on the right side of the decimal point. We would consider the digit after the tenth digit. If this digit is greater than or equal to 5, the tenth digit increases by 1. If it is less than 5, the tenth digit remains the same. In this case, the digit is 6. Since 6 is greater than 5, the tenth digit increases by 1. Thus, the answer is
26.7
