The answer is 8.4
Divide seven by eight. Remember, you will get a number less than one, so place your decimal point.
That is to one decimal place (figures after the decimal point).
It is 7.8
It is then 3.4 rounded up to one decimal place
0.195 = 0.2 rounded to one decimal place
Zero point seven one seven
2.75590551 rounded to the nearest tenths (its one place after the decimal point) is 2.8.
It is 1447.8 mm to one decimal place. There is only one decimal point!
