In the number 70.140, the 1 is the tenth place so to round to nearest tenth place you look at one place over (hundredth) in this case it is the 4. if the number in the hundred place is 5 or greater then you round the number in the tenths one digit up. 
in this case the number in the hundredth place is under 5 so we keep the number in the tenths place,
so the answer would just be 70.1
