Question 1 (Decimal and Base 2 Number System)
Question 1: Convert 15 into an equivalent number with base 2.
a) \( (11111)_2 \) b) \( (12111)_2 \) c) \( (11121)_2 \) d) \( (111111)_2 \)
We should remember that numbers system with base 2 is also called binary number system.
To convert number 15 (decimal number system) to a base number system with base 2 we divide it continuously with 2 till the dividend becomes less than 2 – as shown in the table below;
Then we put remainders in a bracket in the arrow wise direction and write \( (11111)_2 \)
So decimal number 15 is equivalent to \( (11111)_2 \) in base system with base 2.
