I need help. I cant understand how to figure out if the result of a Multiplied Rational Expression can be defined as y=0? I am using Khan Academy but the wording they use is just confusing

Question

Here is the question:

4/5y^3 / 1/12y^6

For the result to be equivalent to the original expression, can it be defined as y=0?

Answer 1

4/5y^3 divided by 1/12y^6

= 4/5y^3 times 12y^6

= 48y^3

if y=0, the the original expression = 0/0 which is undefined and indeterminant, although some argue 0/0 = 1

but 48(0^3) = 0 and can have y=0, and in this case 0/0 does not = 1 or any non zero value
