 #### **`💙  It looks like you are changing/adding files in a Practice Exercise! 💙 `**

**`Please note:`** generally, changes to existing [practice exercises](https://github.com/exercism/docs/blob/main/building/tracks/practice-exercises.md) or the addition
of new ones are proposed & discussed in [problem-specifications](https://github.com/exercism/problem-specifications) first, so that all tracks can potentially benefit.
Once a change is approved there by three maintainers, it becomes available for various language tracks to then implement.

 A rational number is defined as the quotient of two integers `a` and `b`, called the numerator and denominator, respectively, where `b != 0`.
 
+~~~~exercism/note
+Note that mathematically, the denominator can't be zero.
+However in many implementations of rational numbers, you will find that the denominator is allowed to be zero with behaviour similar to positive or negative infinity in floating point numbers.
+In those cases, the denominator and numerator generally still can't both be zero at once.

 The absolute value `|r|` of the rational number `r = a/b` is equal to `|a|/|b|`.
 
 The sum of two rational numbers `r₁ = a₁/b₁` and `r₂ = a₂/b₂` is `r₁ + r₂ = a₁/b₁ + a₂/b₂ = (a₁ * b₂ + a₂ * b₁) / (b₁ * b₂)`.

 Exponentiation of a real number `x` to a rational number `r = a/b` is `x^(a/b) = root(x^a, b)`, where `root(p, q)` is the `q`th root of `p`.
 
 Implement the following operations:
- - addition, subtraction, multiplication and division of two rational numbers,
- - absolute value, exponentiation of a given rational number to an integer power, exponentiation of a given rational number to a real (floating-point) power, exponentiation of a real number to a rational number.

+- absolute value, exponentiation of a given rational number to an integer power, exponentiation of a given rational number to a real (floating-point) power, exponentiation of a real number to a rational number.
 
 Your implementation of rational numbers should always be reduced to lowest terms. For example, `4/4` should reduce to `1/1`, `30/60` should reduce to `1/2`, `12/8` should reduce to `3/2`, etc. To reduce a rational number `r = a/b`, divide `a` and `b` by the greatest common divisor (gcd) of `a` and `b`. So, for example, `gcd(12, 8) = 4`, so `r = 12/8` can be reduced to `(12/4)/(8/4) = 3/2`.

-Given two lists determine if the first list is contained within the second
-list, if the second list is contained within the first list, if both lists are
-contained within each other or if none of these are true.
+Given any two lists `A` and `B`, determine if:
 
-Specifically, a list A is a sublist of list B if by dropping 0 or more elements
-from the front of B and 0 or more elements from the back of B you get a list
-that's completely equal to A.
+- List `A` is equal to list `B`; or
+- List `A` contains list `B` (`A` is a superlist of `B`); or
+- List `A` is contained by list `B` (`A` is a sublist of `B`); or
+- None of the above is true, thus lists `A` and `B` are unequal
+
+Specifically, list `A` is equal to list `B` if both lists have the same values in the same order.
+List `A` is a superlist of `B` if `A` contains a sub-sequence of values equal to `B`.
+List `A` is a sublist of `B` if `B` contains a sub-sequence of values equal to `A`.
 
 Examples:
 
- * A = [1, 2, 3], B = [1, 2, 3, 4, 5], A is a sublist of B
- * A = [3, 4, 5], B = [1, 2, 3, 4, 5], A is a sublist of B
- * A = [3, 4], B = [1, 2, 3, 4, 5], A is a sublist of B
- * A = [1, 2, 3], B = [1, 2, 3], A is equal to B
