Really confused on this.

Step-by-step explanation:

Lets look at A. In A, It says 0.510 is greater than 0.510. That is not true becuase both are equal. A is false.

Lets look at B. In B, it says 0.501 is less that 0.510. This is true. 501 is less than 510. B is true.

Lets look at C. In C, it says 0.061 is greater than 0.510. This is not true becuase 61 is not greater than 510. C is false.

Lets look at D. In B, it says that 0.500 is greater than 0.510. This is not true becuase 500 is less than 510. D is false.

B is the correct answer. I hope this helps! Let me know if I got something wrong so I can fix it.
