Answer:
Step-by-step explanation:
If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.
As an example, if k is 0.5. Then we have
20k = 20 * 0.5 = 10, which is less than 20 and greater than zero
Again, if k is 0.9. Then we have
20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.
So, you use any decimal number greater than 0, yet less than 1
