I THINK THERE ARE FOUR OPTIONS,AM I RIGHT? THE OPTIONS IS 10,11,12, AND 13.IF YOU WANTED TO GET THE ANSWER TRY TO DIVIDE EACH NUMBER (OPTION) OF 121.
Step-by-step explanation:
112÷10= 12.1
112÷11= 11
112÷12= 10.1
112÷13= 9.30
AS YOU CAN SEE ONLY THE OPTION 11 DON'T HAVE A REMAINDER,SO THE ANSWER IS 11.
