Recently, permafrost, which is supposed to be continuously frozen, has been thawing in some places. The photo below is a picture of what is referred to as a "drunken forest."

Answer: -21/7 or -3 (depends on your instruction)
Explanation:
Opposite: the opposite of the current sign
- if it is currently negative [-], then its opposite is positive [+]
- If it is currently positive [+], then its opposite is negative [-]
Reciprocal: changing the place of numerator and denominator
- The reciprocal of a/b is b/a
---------------------------------------------------
7/21
Opposite: since it is positive, the opposite is negative
Reciprocal: since it is 7/21, we change the place, and it is 21/7=3
<h2>Opposite reciprocal of 7/21 is -21/7 or -3</h2>
