Answer:
reciprocal
Explanation:
In mathematics, the reciprocal of a number is essentially the multiplicative inverse of that number. For any non-zero number (a), the reciprocal is (1/a). So, in the case of the number 7, the reciprocal is (1/7). Likewise, for (1/7), the reciprocal is 7. Therefore, 7 is the reciprocal of (1/7) and vice versa. It's a relationship where the product of a number and its reciprocal is always 1: 7* 1/7. This reciprocal relationship is a fundamental concept in arithmetic and algebra.
