No number is divisible by 0. There is no answer, this is supposed to be a trick question.
0/0 is undefined in mathematics, though some calculation software will give it a default value of zero in order to allow further calculations to take place!
It's known as an "indeterminate " form....here's why....
Note 6/3 = 2 because the result times the denominator of the fraction returns the numerator of the fraction
But note....
0 / 0 = could equal any real number because a real number times the denominator of the fraction returns the numerator
However.......since any real number will satisfy this, we can't determine the exact value of that real number.....
Thus...it's indeterminate
