Answer: C
5/6 is the number closest to 1.
The fraction 5/6 is the closest to 1 among the given options, as it is only 1/6 away from 1, making it a smaller distance compared to the other fractions.

B) 5/4
5/4 is equal to 1.25, which is 0.25 away from 1. This is further from 1 than both 4/5 and 5/6, making it less suitable as the closest number.
C) 5/6
5/6 is equal to approximately 0.8333, which is only 0.1667 away from 1. This fraction is the closest to 1 compared to all other options given.
D) 6/5
6/5 is equal to 1.2, which is 0.2 away from 1. This makes it further from 1 than 5/6, confirming that it is not the closest option.
Conclusion
5/6 is definitively the closest number to 1, as it has the smallest difference from 1 compared to all other options provided. The other options either exceed 1 or fall short of being as close as 5/6, which makes them incorrect choices in this context.
