You're chasing the least significant digit. The best accuracy available in the equation is the 'bar 4'. This means the sum is 2.7xx, where the 'xx' (coz I can't find a vinculum on my keyboard) here shows the significant digits stop at the seven, as that's the last significant digit. So the answer is 27/10.
