Convert 7 from decimal to binary (base 2) notation:
Power Test
Raise our base of 2 to a power Start at 0 and increasing by 1 until it is >= 7 20 = 1 21 = 2 22 = 4 23 = 8 <--- Stop: This is greater than 7
Since 8 is greater than 7, we use 1 power less as our starting point which equals 2
Build binary notation
Work backwards from a power of 2 We start with a total sum of 0:
22 = 4
The highest coefficient less than 1 we can multiply this by to stay under 7 is 1 Multiplying this coefficient by our original value, we get: 1 * 4 = 4 Add our new value to our running total, we get: 0 + 4 = 4
This is <= 7, so we assign our outside coefficient of 1 for this digit. Our new sum becomes 4 Our binary notation is now equal to 1
21 = 2
The highest coefficient less than 1 we can multiply this by to stay under 7 is 1 Multiplying this coefficient by our original value, we get: 1 * 2 = 2 Add our new value to our running total, we get: 4 + 2 = 6
This is <= 7, so we assign our outside coefficient of 1 for this digit. Our new sum becomes 6 Our binary notation is now equal to 11
20 = 1
The highest coefficient less than 1 we can multiply this by to stay under 7 is 1 Multiplying this coefficient by our original value, we get: 1 * 1 = 1 Add our new value to our running total, we get: 6 + 1 = 7
This = 7, so we assign our outside coefficient of 1 for this digit. Our new sum becomes 7 Our binary notation is now equal to 111
Final Answer
We are done. 7 converted from decimal to binary notation equals 1112.
What is the Answer?
We are done. 7 converted from decimal to binary notation equals 1112.
