Convert each binary number to decimal:
Each digit to the left is worth twice what it is worth in the column to its right: each column starting from the right is worth 1, 2, 4, 8, 16, 32, ...; for an 8-bit number, the columns from the left are 128, 64, 32, 16, 8, 4, 2, 1; thus :
0000 1010 = 8 + 2 = 10
0110 0100 = 64 + 32 + 4 = 100
0001 0101 = 16 + 4 + 1 = 21
0000 0001 = 1
→ 00001010.01100100.00010101.00000001 = 10.100.21.1
The IPv4 dotted decimal representation is just expressing the 32 bits of the address in the value of each of the 4 bytes used to store the 32 bits using decimal numbers with a dot between each byte's value so that it is not confused to be a single number, ie so that 10.100.21.1 is not read as 10100211 or 10,100,021,001 when the correct decimal value of the 32 bit binary number (0000 1010 0110 0100 0001 0101 0000 0001) is 174,331,137 (but converting that to binary is not as easy as converting an 8 bit (decimal number of range 0-255) to binary.

What is 1090000 as a decimal?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the decimal representation is 1090000, exactly as in the question.

What is decimal in expanded form?
It is the representation in which the decimal number is represented by a sum consisting of each digit as a decimal number with one significant digit.For example 12.345 = 10 + 2 + 0.3 + 0.04 + 0.005
What is the approximate of each irrational?
Every irrational number can be represented by a non-terminating non-repeating decimal. Rounding this decimal representation to a suitable degree will provide a suitable approximation.
What is the decimal representation of 1.4144?

How can the subnet mask for a class C address be represented?
255.255.255.0 - in decimal representation 11111111.11111111.11111111.00000000 - binary representation (3 bytes with all the bits equal to 1, the last byte with all the bits equal to 0) /24 - binary short representation (the number of bits equal to 1)
Which fraction can be represented by a repeating decimal?
If the fraction, in its simplest rational form, has a denominator which has any prime factor other than 2 or 5, then proper representation of the fraction requires the use of repeating decimal.
What is 12.0 in decimal?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 120, exactly as in the question.
What is a non repating decimal and a non termianting decimal?
It is a number whose decimal representation goes on forever without any repeating pattern. It is the decimal representation of an irrational number.
What is .05 as a decimal?
0.5 is already expressed as a decimal.
Can you Explain the use of BCD coding systems in a business environment?
it is used for representing decimal numbers in which each decimal digit is represented by a sequence of binary digits. This makes it relatively easy to convert the numeric representation for printing or display purposes, and speeds up decimal calculations.
What decimal number is represented by the binary number?
Every decimal number can be represented by a binary number - and conversely.
