We have ten fingers (including thumbs) and early counting is based on one-to-one mapping onto these digits. So one reason is simple familiarity.
The other advantage of counting in decimals is that fewer digits are required: 4 decimal digits takes you to over a thousand, you would need 10 binary digits to go over 1024. It gets worse with larger numbers: 7 decimal digits to go over a million but 20 binary digit.
I have phones with 11 digit numbers (without the international country code). In binary, that would be a 33-digit number. No thanks!

Why do people use the decimal system instead of the binary octal or hexadecimal systems?
I think people use the decimal system because we have 10 fingers and it's more intuitive that way. Computers use octal or hex because the base is a power of 2 (8=2^3, 16=2^4), and the computers work in binary, 0 or 1, 2 values.

If you use Windows, you can use the Windows calculator to convert from decimal to binary. Change to scientific mode, be sure the calculator is in decimal, type the decimal number, and switch to binary. If you are practicing decimal to binary conversion, this is a great tool to verify that you have done your calculations correctly.
What is the advantage of having the binary number system to represent data inside the computer instead of the decimal number system?
They use the binary sysem because the number 1 means the switch is turned on and the number 0 means the switch is off. There is no way to use the decimal number system.
What is the binary number of 209.85.153.94?
Just use the Windows calculator, and set it to scientific mode, or use any scientific calculator that supports binary/decimal. In the Windows calculator, make sure you are in decimal, type in each of the four numbers, then select "Binary" to convert to binary. You will have to fill out some of the binary numbers with zeroes to the left (each one must have 8 binary digits).Just use the Windows calculator, and set it to scientific mode, or use any scientific calculator that supports binary/decimal.
