A reciprocal of a number is the value you get by dividing 1 by the number. For example, if you want to find the reciprocal of 10, then you divide 1 by 10 and you get 1/10. You can find the reciprocal of a fraction as well. Thus if you want the reciprocal of 1/10 then you divide 1 by 1/10 which is (1)/(1/10) which yields the original number we started with, namely 10. So 10 and 1/10 are reciprocals of each other. Note also that multiplying any number by its reciprocal will always yield 1.
