To round to 1 decimal place you look at the numbers after the first decimal place onwards. If the value is more than 5 (or 50 or 500 etc) then round up, if the value is less than 5 then round down. If the value is exactly 5, then some statistically naive people suggest round upwards. The correct procedure, so as not to introduce an upward bias, is to round up or down so that the last digit left is even.
Here the number after the first decimal place is 74 - well above 50. So you round up.
