The number 6.25 in the decimal notation, when converted to the binary notation will read as ?


Detailed Solution for Digital Electronics NAT Level - 1 - Question 2


Hence, 6 =110
Now 0.25 x 2 = 0.50 → 0
0.50 x 2 = 1.00 → 1
0.00 x 2 = 0 → 0
Hence, 0.25 = 0.010 →1
Hence (6.25)2 = 110.010
The correct answer is: 110.01
