Unfortunately, the search results provided by You.com do not directly address this specific question. However, we can still provide some insights based on mathematical reasoning.

The expression 20:a represents the division of 20 by 'a'. To obtain a natural number as the result, 'a' must be a divisor of 20. In other words, 'a' must be a positive integer that evenly divides 20 without leaving a remainder.

The divisors of 20 are 1, 2, 4, 5, 10, and 20. Therefore, these are the natural values for 'a' that make the expression 20:a equal to a natural number.

In summary, the natural values for 'a' that make the expression 20:a take natural values are 1, 2, 4, 5, 10, and 20.
