To round to the nearest tenth, we need to explain the situation. Rounding to the nearest tenth is rounding the hundredths place, which is 2 places to the right of a decimal, if it is 5 or higher. If our hundredths place is 5 or higher, we can round up our tenths place, which is 1 place to the right of a decimal.
With the information provided, we can work on our question now.
Our number is 15.83~ (endless). Let's look at our hundredths place for a 5 or higher to determine if we can round or not.
Our hundredths place is 3, so we cannot round up our tenths place. This means that our tenths place will remain 8.
Your answer is 15.8.
I hope this helps!
