    the inverse of a number means that if you multiply the number by its inverse you will get 1. so therefore, to work out the inverse you do 1 divided by the number.

    Let me show you the DEFINING equation for reciprocals again: $$a*b=1$$ When asked to find the reciprocal of a number replace one of the letters in this equation with that number and solve for the other letter, for example: what is the reciprocal of 2? So $$2*b=1$$ What number multiplied by 2 gives 1?

    Let me try and explain why you can never divide by 0. Dividing by 0 would mean multiplying by the reciprocal of 0, but 0 has no reciprocal because 0 times ANY number is 0, NOT 1.
