Answer:
The first one is wrong whereas the second one is correct.
Step-by-step explanation:
a) 1÷a= 1/a is the correct answer and not 1.
b) a÷(-1)= - a/ 1 = -a ( since 1 is there in the denominator)
1 if present in the numerator has a significant value whereas if present in the denominator has no value.
In the first case, since the 1 is present in the numerator it comes in the resultant whereas in the second case it has no value.
