WHAT IS 20 percent OF 4800?
960 The easiest way to work out a percentage of something, is to convert the percentage into a decimal. 20% can also be written as 0.2 as a decimal. You can then multiply 4800 by 0.2. This works with any number as well. When the percentage is more difficult and you do not have a calculator, you can work out 10%, and then multiply that answer by 2 (to get 20%) Hope this helped :D
What are the advantages and disadvantage of BCD number system?
AdvantagesMany non-integral values, such as decimal 0.2, have an infinite place-value representation in binary (.001100110011...) but have a finite place-value in binary-coded decimal (0.0010). Consequently a system based on binary-coded decimal representations of decimal fractions avoids errors representing and calculating such values.Scaling by a factor of 10 (or a power of 10) is simple; this is useful when a decimal scaling factor is needed to represent a non-integer quantity (e.g., in financial calculations)Rounding at a decimal digit boundary is simpler. Addition and subtraction in decimal does not require rounding.Alignment of two decimal numbers (for example 1.3 + 27.08) is a simple, exact, shift.Conversion to a character form or for display (e.g., to a text-based format such as XML, or to drive signals for a seven-segment display) is a simple per-digit mapping, and can be done in linear (O(n)) time. Conversion from pure binary involves relatively complex logic that spans digits, and for large numbers no linear-time conversion algorithm is known (see Binary numeral system).[edit]DisadvantagesSome operations are more complex to implement. Adders require extra logic to cause them to wrap and generate a carry early. 15-20 percent more circuitry is needed for BCD add compared to pure binary. Multiplication requires the use of algorithms that are somewhat more complex than shift-mask-add (a binary multiplication, requiring binary shifts and adds or the equivalent, per-digit or group of digits is required)Standard BCD requires four bits per digit, roughly 20 percent more space than a binary encoding (the ratio of 4 bits to log210 bits is 1.204). When packed so that three digits are encoded in ten bits, the storage overhead is greatly reduced, at the expense of an encoding that is unaligned with the 8-bit byte boundaries common on existing hardware, resulting in slower implementations on these systems.Practical existing implementations of BCD are typically slower than operations on binary representations, especially on embedded systems, due to limited processor support for native BCD operations.
What happens to binary numbers over 255?
You simply use more binary digits.
How do you convert decimal 98 to an 8-bit binary value?
You convert 98 base 10 into 1100010 base 2 the same way you convert any decimal number into a binary number. You iteratively divide by 2, recording the remainders in reverse order, until the quotient is zero.98 / 2 = 49 remainder 049 / 2 = 24 remainder 124 / 2 = 12 remainder 012 / 2 = 6 remainder 06 / 2 = 3 remainder 03 / 2 = 1 remainder 11 / 2 = 0 remainder 1So the result, reading backwards (up) is 1100010 base 2.and as an 8 bit value it would be 01100010.The more general answer is that, to convert a number in any base to any other base, iteratively divide the first number by the second base, using the rules of arithmetic of the first base, recording the remainders in reverse order, until the quotient is zero. The remainders then need to be written in terms of the second base.
What are decimal numbers with decimal points before and after the decimal point called?
There can be no number that has more than one decimal point.
Why is it more difficult to convert decimal to hexadecimal?
As compared to converting decimal into what other base! It is no more difficult to convert decimal into base 8 than decimal into binary or Hex.
Why is creating a converter from decimal to binary more difficult?
The answer depends on what the comparison is with! It is not more difficult than proving the Goldbach conjecture, for example.

Write a c program to convert binary number to decimal number?
How is this a question? Sounds like you should do more of your homework offline.
How many megabytes are in 100 megabytes?
100, 104.858, or 95.367, depending on if you mean decimal to decimal, binary to binary, decimal to binary, or binary to decimal. Simply, decimal megabytes, used by the storage industry, is 1,000KB, where each KB is 1,000 bytes. Binary megabytes, used by programmers (such as Microsoft, Linux, etc) are 1,024 KB, where each KB is 1,024 bytes (2^10, or 0x0200). Converting from decimal to binary will yield a smaller number of megabytes, while converting from binary to decimal will result in more megabytes.
What is a googolplex in binary?
Good grief! We can't even write out a googolplex in decimal! How are you going to write it out in binary?
How will you Convert this binary number 111111111111 into hexadecimal?
4095 For anything more complex I would use the standard 'calculator' provided with Windows, click on 'View' then 'Scientific'. The radio buttons let you select Decimal, Hex, Octal or Binary for the currently displayed number.
Is there a formula that can be used to convert Binary to decimal that is straight forward?
If you mean a straight forward algorithm, then yes.I guess you want to know what it is...Start at the left hand end of the binary number with the result (decimal number) set to zerodouble the result and add the current binary digitif there are more binary digits move one binary digit to the right and repeat step 2repeat steps 2 and 3 until all the binary digits have been used.the result is the decimal equivalentfor example converting 101002 to decimal:1. set result to 0, start with the first binary digit (of 10100) which is 12. 2 x 0 + 1 = 13. 2nd binary digit (of 10100) is 02. 2 x 1 + 0 = 23. 3rd binary digit (of 10100) is 12. 2 x 2 + 1 = 53. 4th binary digit (of 10100) is 02. 2 x 5 + 0 = 103. 5th binary digit (of 10100) is 02. 2 x 10 + 0 = 203. no more binary digits4. 101002 = 2010
What is Binary to Hexa?
Just separate all the numbers in groups of four look (1011101.01101100)2 to hexa 0101 1101. 0110 1100 Then replace the binary numbers for hexa numbers 01012= 516 11012=D16 01102=616 11002=C16 so (1011101.01101100)2 = (5D.6C)16
What is the value of pi to 20 or more?
In binary: 11.00100100001111110110 In Decimal: 3.14159265358979323846 In hexadecimal: 3.243F6A8885A308D31319
Why binary number need more space?
For the simple reason that the 'places' in a binary number represent multiples of 2, rather than 10. Therefore, a binary '10' = a decimal '2.'
