When rounding to the tenth, look at the next number (in your case, in the 100th column)... if it is 5 or greater, then add 1 to the tenth spot and drop the rest. If it's less than 5, then just drop the rest.
So, 7.93 rounded to the nearest tenth would be 7.9.
7.95, however, would be 8.0 (add 1 to the tenth)
It is 232.4 when rounded to the nearest tenth
It is then 20.2 when rounded to the nearest tenth

Well, isn't that a happy little number! When we round 5.167 to the nearest tenth, we look at the digit in the hundredths place, which is 6. Since 6 is greater than 5, we round up the tenths place, making it 5.2. And just like that, we have a beautifully rounded number!
