What is it? can you write out the problem.
I believe you are right I checked the work and everything seems to be good !
D.) 2.13 < 2.3 is correct. This is stating that 2.3 is greater than 2.13, which is true. In the other possible answers, for example 4.15 > 4.51, this would be false because 4.15 is not greater than 4.51. The open end of the greater than or less than sign will always point to the bigger number.
