Why isn't it possible to divide a factor with 0? And if so, what is the answer? 0? ∞?
zavuch27 [327]

let's think about it, let's divide say hmmm 15 by 0, in a fraction

\bf \cfrac{\textit{part of a pie}}{\textit{whole pie}}\qquad \cfrac{15}{0}\implies \cfrac{\textit{taking 15 pieces}}{\textit{from a whole pie that's 0, or not there}}

now, how can you take any pieces of a pie that's non-existent? I mean that requires magic!!.

now, let's do it using a simple long division, 15 ÷ 0, so 0 is the divisor, anything times 0 is 0, what is our first digit in the quotient to get 15? 0 * 15 = 0, 0 * 1,000,000 = 0, there isn't any number we can possible use to get a quotient.
