To convert a binary number into hexadecimal we first break the binary number into substrings of 4 binary numbers , in this case our binary number becomes 1011 | 1000 We then recall that hexadecimal numbers range from 0-9 and A-F where A=10,B=11,C=12,D=13,E=14,F=15 converting each substring to denary we get 13|8 =D|8=D8 in hexadecimal. note that student may need help with converting binary to denary
