Convert 248 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 >= 248
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64
27 = 128
28 = 256 <--- Stop: This is greater than 248
Since 256 is greater than 248, we use 1 power less as our starting point which equals 7
Build binary notation
Work backwards from a power of 7
We start with a total sum of 0:
27 = 128
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 128 = 128
Add our new value to our running total, we get:
0 + 128 = 128
This is <= 248, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 128
Our binary notation is now equal to 1
26 = 64
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 64 = 64
Add our new value to our running total, we get:
128 + 64 = 192
This is <= 248, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 192
Our binary notation is now equal to 11
25 = 32
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 32 = 32
Add our new value to our running total, we get:
192 + 32 = 224
This is <= 248, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 224
Our binary notation is now equal to 111
24 = 16
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 16 = 16
Add our new value to our running total, we get:
224 + 16 = 240
This is <= 248, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 240
Our binary notation is now equal to 1111
23 = 8
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
240 + 8 = 248
This = 248, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 248
Our binary notation is now equal to 11111
22 = 4
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 4 = 4
Add our new value to our running total, we get:
248 + 4 = 252
This is > 248, so we assign a 0 for this digit.
Our total sum remains the same at 248
Our binary notation is now equal to 111110
21 = 2
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 2 = 2
Add our new value to our running total, we get:
248 + 2 = 250
This is > 248, so we assign a 0 for this digit.
Our total sum remains the same at 248
Our binary notation is now equal to 1111100
20 = 1
The highest coefficient less than 1 we can multiply this by to stay under 248 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
248 + 1 = 249
This is > 248, so we assign a 0 for this digit.
Our total sum remains the same at 248
Our binary notation is now equal to 11111000
Final Answer
We are done. 248 converted from decimal to binary notation equals 111110002.
