Answer: Yes, this is possible with only one step, we need to subtract 5.94 of the number 26,583.
Explanation:
This can be translated to:
"Micol said that she can transform the 26.583 into 20.543 with only one step.
Is this possible? why?"
We have no rules here, so we can try with the shortest path.
A subtraction.
If we took 26.583, we know that there exist an number X such:
26.583 - X = 20.543
then we can solve that for X and find:
X = 26.483 - 20.543 = 5.94
So the step that Micol is refering to is subtracting 5.94 of 26.583.
