How do you convert binary number base2 to decimal base10?
Multiply the digit to the left of the "decimal" point by 2^0 = 1. Multiply the digit to the left of it by 2^1 = 2 Multiply the digit to the left of that by 2^2 = 4 and so on. Also Multiply the digit to the right of the "decimal" point by 2^(-1) = 1/2. Multiply the digit to the right of that by 2^(-2) = 1/4 and so on. Add all these together. Example: Binary 1101.1011 1*2^3 = 1*8 = 8 1*2^2 = 1*4 = 4 0*2^1 = 0*2 =0 1*2^0 = 1*1 = 1 1*2^-1 = 1*1/2 = 0.5 0*2^-2 = 0*1/4 = 0 1*2^-3 = 1*1/8 = 0.125 1*2^-4 = 1*1/16 = 0.0625 Sum = 13.6875

There are 60 possibilities that can be made for a three digit number using the numbers 2 4 6 8 and 9 how many of these three digit numbers are smaller than 500?
If this is a homework assignment, please consider trying it yourself first, otherwise the value of the reinforcement to the lesson offered by the homework will be lost on you.There are 60 possibilities that can be made for a three digit number using the numbers 2 4 6 8 and 9. (5 choices for the first digit, 4 choices for the second digit, and 3 choices for the third digit - multiply 5, 4, and 3, and you get 60.)To determine how many of these three digit numbers are smaller than 500, consider that, given 2 4 6 8 and 9, the first digit would have to be 2 or 4. That gives 2 choices for the first digit, 4 choices for the second digit, and 3 choices for the third digit. Multiply 2, 4, and 3, and you get 24.
