Final answer:
The number 10 is the one that does not belong because it is a whole number and is not commonly represented as a fraction, unlike 10/100 which simplifies to 0.1.
Step-by-step explanation:
The question asks which number does not belong between 10/100 and 10. The fraction 10/100 simplifies to 0.1, which is equal to 10^(-1). In contrast, 10 is equal to 10^(1). When considering the value of these numbers, 10 does not reduce or is not commonly shown as a fraction, therefore 10 is the number that does not belong in the context where we are comparing a non-reduced fraction to a whole number.
