Answer:
you can't convert 1011.112 to hex. the reason is simple bcz to convert into hex, first you have to convert in the binary value which must be vary between 0 and 1 only.
here you used 2 i;e 1011.112, and remember we don't use any no. except 0 and 1.
but you can change 1011 which is "B" in hexadecimal.
so the answer is "B.112"
