What is the decimal number of binary number `(111001.01)_(2)`?

A

9.625

B

25.265

C

26.625

D

26.265

Text Solution

Verified by Experts

The correct Answer is:
C
`(11010.101)_(2)=(11010)_(2)+(0101)_(2)`
`=[0xx2^(0)+1xx2^(1)+0xx2^(2)+1xx2^(3)+1xx2^(4)]+[1xx2^(-1)+0xx2^(-2)+1xx2^(-3)]`
`=[0+2+0+8+16]+[1/2+0+1/8]`
`=26+5//8=26.625`
