Can you help me solve problem 2 forme plz

Here is the answer

2 a)

To convert forget about '.'

Group in group for 4 bits from end like this

111 0101 1000 1011

If first group is having less bits (111 in this case) prepend 0's to make it 4 bit group

so now it will be 0111 0101 1000 1011

0111 -> 7 in decimal and 7 in decimal is 7 in hex

0101 -> 5 in decimal and 5 in decimal is 5 in hex

1000 -> 8 in decimal is 8 in hex

1011 -> 11 in decimal is B in hex

So conversion will be 758B

similarly

2 b)

10110011101.11

1 0110 0111 0111

0001 0110 0111 0111

0001 -> 1

0110 -> 6

0111 -> 7

0111 -> 7

so hex is 1677
