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

Carl is drawing blueprints for a new building. Although the building will be 40 feet (480 inches) tall, his drawing is only 10 i
STatiana [176]

Answer:

48:1

Step-by-step explanation:

In this case we know the actual size and the size in the drawing therefore we can calculate its scale.

What we must do is divide the actual size by the size in the drawing. We know the actual size is 480 inches and in the drawing the size is 10 inches, so:

480/10 = 48

Which means that the relationship between the real and the drawing is 48:1

Explain how to model the division of –24 by –4 on a number line.
lianna [129]

Answer:

Here's one way to do it.

Step-by-step explanation:

-24 ÷ (-4)

-24 is the final number on the number line

-4 means you count by 4s on the number line moving backwards.

  1. Start at 0 facing forward.
  2. Move backwards in steps of four units from 0 to -24.
  3. Count the number of steps you took (six).

Answer: +6 (The sign is + because you are still facing forward).
