Answer:
27.1
Step-by-step explanation:
Rounding off to the nearest tenths = the value should be written correctly to <u>one</u> decimal place. The tenth place value in a decimal number is the first number which comes first after the decimal point. For this, we need to observe the hundredth number (the number which comes second after the decimal point). If this number is greater than or equal to 5, we add 1 to the tenth value. If it is less than 5, we leave the tenth place value as it is, and remove all the numbers present after this number.
