Ok since you don't have a calculator you do it like this:
1. 830 / 150 = 5.533333
However since 0.83 is not a whole number and 150 has 3 digits, the actual answer is 5.53333 X 10^-3,
which is just 0.00553333.
2. 385/ 700 = 0.55, not the same as before. You have now 38.5 which has 2 digits that are whole numbers. So the final answer is just 0.055
