In case of rounding to nearest tenth, we check the digit in hundredths place.
if it is equal to or greater than 5, we increase the digit in tenths place by 1
if it is less than 5 , we keep the digit in tenths place same
5.368 , here digit in hundredth place is 6, which is greater than 5, so rounding off we get 5.4
