Question

How do you express the place values in the binary number system which uses base 2 and in the octal number system which uses base 8?

Answer 1

if you want to convert them then first convert binary to Decimal form
for example:

11000

1*2^0 =1
1*2^1 =2
0*2^2=0
0*2^3=0
0*2^4=0
= 3
then convert 3 into octal

3/8= (as 3 is less then 8 is remains same) 3
