Answer: C

Explanation:

4.4 is the greatest value among the options.

When comparing the given values, 4.4 is the highest numerical value, surpassing the others in magnitude.

A) 4.25

4.25 is less than 4.4, making it an incorrect choice. While it is a significant value, it does not exceed 4.4.

B) 9/2

9/2 equals 4.5, which is greater than 4.4. Therefore, this option is incorrect as 4.5 exceeds 4.4.

C) 3/10

3/10 equals 0.3, which is much lower than 4.4. Thus, this option is also incorrect as it does not approach the value of 4.4.

D) 4.4

4.4 is equal to itself and is indeed the greatest value when compared to the other options provided.

Conclusion

The greatest value among the options is 4.4, which clearly surpasses the other values presented. While some options are close, none exceed 4.4, confirming it as the correct answer.
