It is easy to convert the binary number to gray number. First, for example take a binary number i.e ,101101.

Step 1: 101101 first write the MSB as it is i.e, darken bit i.e, 1

Step 2: add MSB and bit next to the MSB i.e, 1+0=1

Step 3: again add 0 and 1 we get i.e, 0+1=1

Step 4: again add 1 and 1 we get 1+1=0

Step 5: in previous step carry is occurred so neglect that carry . note that don't add carry to next add numbers

then again add 1+0 1+0=1

step 6: add 0+1 0+1= 1

Answer: Gray Code is : 111011
