a) Can you explain your answers to the previous two questions. Why are they different?

a
The order of rounding and doing a calculation is important. Take $3.22$ and $6.94$. Looking at the second decimal place, when rounded first they both round down. However, when added first, it becomes $10.16$ which rounds up. Hence the difference.
