Answer:
The digit that fit into the blank space is 6
Step-by-step explanation:
Here, we want to enter digits into the blank space that can make the expression valid.
Let’s try 6;
6583 < 6612 < 6687
This is actually correct.
Can we have any other digit here?
No, i don’t think so.
Putting in a 5 will make the first number greater than the middle
Putting in a 7 will make the middle number greater than the last and thus render the expression invalid
