When using bits to represent fractions of a number, can you create all possible fractions?.
mafiozo [28]

Every rational number has a base-2 representation, but only the ones with denominators that are powers of 2 will require a finite number of bits to fully represent it.

For example,

\dfrac12 = 1\cdot2^{-1} = 0.1_2

\dfrac14 = 1\cdot2^{-2} = 0.01_2

\dfrac34 = \dfrac12 + \dfrac14 = 0.11_2

\dfrac{1023}{1024} = 1 - \dfrac1{2^{10}} = 1_2 - 0.0000000001_2 = 0.1111111111_2

whereas a number whose denominator contains anything else like 1/3 will need an infinite number of bits to represent it exactly.

\dfrac13 = \dfrac1{2^2} + \dfrac1{12} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{48} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{2^8} + \dfrac1{192}

and so on, so that it has a repeating but non-terminating base-2 representation

\dfrac13 = 0.010101\ldots_2

4a. If (11+x) is positive, but (4+x) is negative, what is one number that x could be?
sattari [20]

Answer:

Step-by-step explanation:

x has to be equal to or less than a -5 to get (4 + x) to be a negative number.

x has to be equal to or greater than -10 for (11 + x) to be a positive number.

Therefore, any number between -10 and -5 will work.
