C

Which statement BEST explains the conversion of the binary number 1010 to a decimal number? A. 1010 in binary equals 20 because 10 plus 10 equals 20 and binary means the value of every two numbers added together gives the decimal number. B. 1010 in binary requires you to take the digits and add them together and raise them to the 10th power to get a decimal value so 210 is 1024 in decimal value. C. Moving from left to right, the first 1 is 23; the first 0 is 22; the second 1 is 21 and second 0 is 20 therefore the binary number is equal to the decimal number 10 because 23 =8 and 21 =2 and 8 plus 2 equals 10. D. Moving from left to right, the first 1 is 24; the first 0 is 23; the second 1 is 22 and second 0 is 21 therefore the binary number equals to the decimal number 10 because 24 =16 and 22 =2 and 16 plus 4 equals 20.
