Answer 2

Converting Decimal to Binary

To convert the decimal number 30 to binary, we can use the division-by-2 method. Here's how it works:

1. Divide the decimal number by 2. 2. Write down the remainder (0 or 1). 3. Repeat steps 1 and 2 with the quotient obtained in step 1. 4. Continue this process until the quotient becomes 0.

Let's apply this method to convert 30 to binary:

1. Divide 30 by 2: 30 ÷ 2 = 15, remainder 0. 2. Divide 15 by 2: 15 ÷ 2 = 7, remainder 1. 3. Divide 7 by 2: 7 ÷ 2 = 3, remainder 1. 4. Divide 3 by 2: 3 ÷ 2 = 1, remainder 1. 5. Divide 1 by 2: 1 ÷ 2 = 0, remainder 1.

Now, let's read the remainders from bottom to top: 11110.

Therefore, the binary representation of the decimal number 30 is 11110.
