Converting decimals to binary
How do you convert the numbers?
CONVERT DECIMAL NUMBERS TO BINARY
To convert a decimal number to binary, all you have to do is divide the number by 2. Get the quotient and the
remainder. Bring down the quotient, divide it by 2, and get the quotient and remainder again. Do it repeatedly
until the quotient results to 0. Copy the remainder from bottom to top, and that is the binary equivalent.
Abstract:
What do you need to know before converting decimals to binary?
DIGITAL REPRESENTATION
Within a computer, information is represented and stored in a digital binary format. The term bit is an
abbreviation of binary digit and represents the smallest piece of data. Humans interpret words and pictures;
computers interpret only patterns of bits. A bit can have only two possible values, a one digit (1) or a zero
digit (0). A bit can be used to represent the state of something that has two states. For example, a light switch
can be either On or Off; in binary representation, these states would correspond to 1 and 0, respectively.
Computers use binary codes to represent and interpret letters, numbers and special characters with bits.
A commonly used code is the American Standard Code for Information Interchange (ASCII).
With ASCII, each character is represented by a string of bits. For example: Capital letter: A = 01000001 Number:
9 = 00001001 Special character: # = 00100011 Each group of eight bits, such as the representations of letters
and numbers, is known as a byte. Codes can be used to represent almost any type of information digitally:
computer data, graphics, photos, voice, video, and music.
Application:
There will be a Game Activity (The first group that raised the correct answer got the point)

Group Activity: Convert Decimal Number to Binary Number
Instruction: The group with most number of correct answer win.
1. 44 = 101100
2. 65 = 1000001
3. 29 = 11101
4. 49 = 110001
5. 97 = 1100001
IV
