#1 1001 0010

Ans. For converting Binary to decimal = 1*2⁷+0*2⁶+0*2⁵+1*2⁴+0*2³+0*2²+1*2¹+0*2⁰ = 146

#2 0111 0111

Ans. For converting Binary to decimal = 0*²⁷+1*²⁶+1*²⁵+1*²⁴+0*²³+1*²²+1*²¹+1*²⁰ = 119

Similarly, do the other questions(#3-#12).

An easy method to convert decimal to binary number equivalents is to write down the decimal number and continually divide-by-2 (two) to give a result and a remainder of either a “1” or a “0” until the final result equals zero.

#1 238

Ans. 11101110

#2 34

Ans. 00100010

Similarly, do the other questions(#3-#12).

Using the table provided in the first task, identify which class each of the following addresses belongs to.
