Answer 2

The equivalent binary number of decimal number 15 is 1111.

• Binary numbers are those numbers that are used in computer language and are only represented by 0 and 1.
• Decimal numbers are those numbers that are used in mathematics and computer language. These are represented or formed using 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
• To change from binary to decimal number system we use the long division method and keep the remainder to get answers.
• The remainder which is kept is written from downward to upward to get the answer.
• Firstly, by taking 15 and dividing it by 2 we get the quotient 7 and the remainder 1.
• Then, by taking 7 and dividing it by 2 we get the quotient 3 and the remainder 1.
• Then, by taking 3 and dividing it by 2 we get the quotient 1 and the remainder 1.
• Then, by taking 1 and dividing it by 2 we get the quotient 0 and the remainder 1.
• We can represent our answer as (15)₁₀ = (1111)₂
