$\frac {0}{0}=\nexists$ So No is the answer

Hmmm... Your answer is correct, but what if you substitute 'a' with your profile photo :D

Ashish Siva's answer is right if and only if Abda Ji-a doesn't change the profile picture.

$\frac{∞}{∞}$ is indefinite too. Then so it is possible.

Infinity over infinity and zero over zero are examples of indeterminate forms. They are, well, as said, unable to determine their value (limit).

Let we assume a = 0. Then, it will be 0/0

We can write it as 100 - 100 / 100 - 100 => (10)² - (10)² / 10 (10 - 10) => (10 + 10)(10 - 10) / 10(10 - 10) => (10+10) / 10 => 20/10 => 2.

So, it's not neccesary that a/a = 1

you are wrong!!! you can't write $\frac{0}{0}=\frac{100-100}{100-100}$ even you can't proceed a single step after that

please correct your solution!!!

thanks :-) :-)

You cannot divide 0 by 0 and write 1 instead. =]
