Can you explain how you got 7/1 because I calculate -7/17 for the reciprocal of 1/7 (-7-10).

To find the reciprocal of a fraction, you simply need to "flip" the fraction or interchange the numerator and the denominator. In this case, we need to find the reciprocal of 1/7.

To do this:

Step 1: Flip the fraction by interchanging the numerator and the denominator. Therefore, the reciprocal of 1/7 becomes 7/1.

Step 2: Simplify the resulting fraction if possible. In this case, the fraction 7/1 is already in its simplest form, so we do not need to simplify it further.

So, the reciprocal of 1/7 is indeed 7/1, which can also be written as the whole number 7.
