Question 1: What is reciprocal? For example, there is a score. Two thirds. The reciprocal is to change the position of numerator and denominator. So the reciprocal of two thirds is three thirds. Understand?

Question 2: What is a reciprocal relationship? The two products of 1 are reciprocal, and 0 has no reciprocal. This is called a reciprocal relationship.

Question 3: What is the reciprocal of-7? -7/ 1

Question 4: What is the meaning of reciprocal in mathematics? For example, what is the reciprocal of five? Reciprocal refers to mathematically setting a number whose product x is 1, recorded as 1/x or x, and the process is "multiplication inverse"; If ab= 1(a and b≠0), then A and B are reciprocal. The reciprocal of 5 is 1/5 (one fifth).

Question 5: What does reciprocity mean? What's the difference between reciprocal and reciprocal? For example, half, its reciprocal is 2.

Question 6: What are the reciprocal (reciprocal 1) of two rational numbers whose reciprocal product is 1?

Two rational numbers whose product is-1 are reciprocal.

If A and B are reciprocal, AB =1;

If A and B are negative reciprocal, ab=- 1.

Note: (1) Zero has neither reciprocal nor negative reciprocal.

(2) When a ≠ 0, the reciprocal of a is.

(3) To find the reciprocal of a fraction, just reverse the numerator and denominator of this fraction.

(4) The reciprocal of a positive number is positive, and the reciprocal of a negative number is still negative.
