write down the step to convert binary number into decimal number.

Dear student,
Please find below the answer:

Let 110 be the binary number. To convert it into a decimal number:

• Multiply the rightmost digit by 2⁰ to 0 , then 2¹ to 1, then  2² to 1.
• Add them- 2²*1 + 2¹ *1 + 2⁰ *0

                          = 4*1 + 2*1 + 1*0
                          = 4 + 2 + 0 = 6​​​​​​
Hence the decimal number of binary form 110 is 6.

Hope this clears your doubt.
Regards.
