Reciprocal is a mathematical term. Mathematically, it means that the product of a number x multiplied by it is 1, which is recorded as 1/x, and the process is "multiplication inverse". All numbers except 0 have reciprocal, and the numerator and denominator, in turn, are the reciprocal of 1, and 0 has no reciprocal. , the reciprocal of the wrong score. It's simple. Commutator numerator and denominator are reciprocal of true fraction and false fraction.

2. The reciprocal of an integer. Integer as denominator, 1 as numerator. Is the reciprocal of an integer.

3, the reciprocal of the decimal. For the reciprocal of divisible number, you can divide by 1 to find the reciprocal, for uncountable number, convert the component number, and then find the reciprocal according to the method of true and false fraction.

4, and the reciprocal of the score. First, turn the fraction into a false fraction, then switch the numerator and denominator, which is the reciprocal of the number.
