i get the reciprocal of a number because we all know that the number has an already 1 under it but we can't see it.Just like for example 0.8 atomatic nana sya nga naay 1 sa ubos sa 0.8 (0.8/1). So the question is what is the reciprocal of 0.8 so all we need to do is transfer the 1 into the numerator and 0.8 is a denominator (1/0.8).
