Answer:

73.72

Explanation:

For this subtraction problem, the answer or solution is expressed to the least precise of the numbers we are trying to subtract.

The least precise number is the number with the lowest significant numbers:

105.4 - 31.681

105.4 has 4 significant numbers

31.681 has 5 significant numbers

So;

105.4

- 31.681

------------------

73.719

----------------

The solution is therefore 73.72
