Answer:
The answer is 
Step-by-step explanation:
Firstly, you have to know the position of the tenth decimal.
Give a decimal number, for example, 
The position of the tenth decimal places to the right of the decimal point. In this case, the number 3 is in the position of the tenth place.
Also, you have to know how to round a decimal number. The rule says:
If you want to round a number with a n-decimal digits, you have to see the position n+1-decimal digit:
If this number is equal or greater than 5, you have to increase the n-decimal digit to the next whole number.
If this number is lesser than 5, you have to decrease the n-decimal digit to the previous whole number.
Using the example 
If we want to round the decimal number to the nearest tenth, the next digit is a 2, so we dont increase the number 3. So the decimal number is 114.3
Finally, responding your question,
First you have to represent the fraction number into decimal number.

The nearest tenth is the first decimal digit: 7
The next number is a 9, so if we want to round to the nearest tenth, we will have to increase the number 7 to the next whole number: 8
The final answer is
