Conversion of Binary Number to Decimal Value:

Consider the table given below,

Binary Position	27	26	25	24	23	22	21	20
Decimal Value	128	64	32	16	8	4	2	1

The above table helps to convert each binary number to decimal value.

Given:

(11011011)₂ = ?

Solution:

11011011 = (1*128) + (1*64) + (0*32) + (1*16) + (1*8) + (0*4) + (1*2) + (1*1)

                = 128 + 64 +16 +8 +2 +1

                = 219

Answer:

Hence, the decimal value of (11011011)₂₌ (219)₁₀

Given:

(01111111)₂ = ?
