Question

convertion to binary

Answer 1

Do you want to learn how to do it? See above.

Do you just want to know the results? Look here:

Don't forget that if you want to convert a binary number, it should have 0b at the beginning, or Google Calculator will interpret it as a decimal number.

Answer 2

binary- Bits turned on and off
1 = turned on
0 = turned off

127
Work with powers of two
2^0 = 1, 2^1= 2, 2^2= 4, 2^3=8, and so on.

binaries work in placeholders - always work right to left
10000000 = 128
the 8th bit is 128 or 2^7 (it's turned on so) in decimal it's 128
7th=64, 6th=32, 5th=16, 4th=8, 3rd=4, 2nd=2, 1st=1

if you had more bits the exponents would keep counting 2^x

Now from binary to decimal.
100111001
1st bit on = 1
2nd off = 0
3rd off= 0
4th on= 16
5th on= 32
6th on= 64
7th off= 0
8th off= 0
9th on= 256
Now add the values up and you should get decimal of: 313
