Convert 143 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 >= 143

20 = 1

21 = 2

22 = 4

23 = 8

24 = 16

25 = 32

26 = 64

27 = 128

28 = 256 <--- Stop: This is greater than 143

Since 256 is greater than 143, 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 143 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 <= 143, 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 143 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 > 143, so we assign a 0 for this digit.

Our total sum remains the same at 128

Our binary notation is now equal to 10

25 = 32

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 32 = 32

Add our new value to our running total, we get:
128 + 32 = 160

This is > 143, so we assign a 0 for this digit.

Our total sum remains the same at 128

Our binary notation is now equal to 100

24 = 16

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 16 = 16

Add our new value to our running total, we get:
128 + 16 = 144

This is > 143, so we assign a 0 for this digit.

Our total sum remains the same at 128

Our binary notation is now equal to 1000

23 = 8

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:
128 + 8 = 136

This is <= 143, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 136

Our binary notation is now equal to 10001

22 = 4

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 4 = 4

Add our new value to our running total, we get:
136 + 4 = 140

This is <= 143, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 140

Our binary notation is now equal to 100011

21 = 2

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 2 = 2

Add our new value to our running total, we get:
140 + 2 = 142

This is <= 143, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 142

Our binary notation is now equal to 1000111

20 = 1

The highest coefficient less than 1 we can multiply this by to stay under 143 is 1

Multiplying this coefficient by our original value, we get: 1 * 1 = 1

Add our new value to our running total, we get:
142 + 1 = 143

This = 143, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 143

Our binary notation is now equal to 10001111

Final Answer

We are done. 143 converted from decimal to binary notation equals 100011112.


What is the Answer?

We are done. 143 converted from decimal to binary notation equals 100011112.
