15 in the hexadecimal number system is represented by 21 in the decimal system.
No. Not in hexadecimal, but yes if you are counting in base 21, for example.
22 + 21 + 20 + 0 + 2-2 equals 7.25
The mixed number equivalent to 2.125 is 21/8
-0.84 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is -84/100 which simplifies to -21/25.
15 in the hexadecimal number system is represented by 21 in the decimal system.
16 + 4 + 1 =21
A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the decimal representation for 21 is 21 and therefore the answer is 21 shillings.

31.... Why? 24 + 23 + 22 + 21 + 20 = 16 + 8 + 4 + 2 + 1 = 31 or 25 - 1 = 31 ------------------------------------------------------------------- You can calculate the decimal equivalent of any binary number by adding the powers of two that correspond to each place that a binary digit '1' is in. With decimal numbers, as you move left one digit, from the rightmost digit, you multiply that digit's value by 10. In binary, you multiply that place value by 2. For any eight bit binary number (or less) here are the multiples of 2. We always start with (n-1) for the leftmost exponent, because you have to remember that the rightmost exponent is always 0. 27 + 26 + 25 + 24 + 23 + 22 + 21 + 20 which correspond with the following decimal numbers: 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 All you have to do is add the decimal numbers that correspond with the each binary digit 1 is in. ie. 10000000 (binary) = 128 11000000 (binary) = 128 + 64 = 192 FYI here are the decimal equivalents for four bit binary numbers: 0000 = 0 0001 = 1 0010 = 2 0011 = 3 0100 = 4 0101 = 5 0110 = 6 0111 = 7 1000 = 8 1001 = 9 1010 = 10 = a (in hexadecimal) 1011 = 11 = b (in hexadecimal) 1100 = 12 = c (in hexadecimal) 1101 = 13 = d (in hexadecimal) 1110 = 14 = e (in hexadecimal) 1111 = 15 = f (in hexadecimal)
22 + 21 + 20 + 0 + 2-2 equals 7.25
21/25
One method: Take the decimal number, divide by 16. The remainder of the division will be the least significant (rightmost) digit of the hexadecimal number. (Of couse, convert 10 to a, 11 to b, etc.) Take the quotient from the previous step, divide it by 16. The remainder will be the next digit of the hexadecimal number (going right to left). Repeat until the quotient is 0. Example: Convert 300 to hexadecimal. 300/16 = 18 Remainder 12 (12 is c in hex). 18 /16 = 1 remainder 2. 1/16 = 0 remainder 1. So the hexadecimal number is 12c.
A number which is given to sextillionths.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 21 is 21 – as in the question.
.021 thousandths goes out to the 3rd place after the decimal. Put the number down so it goes out three places after the decimal point, put zeros before it if you need to. Putting decimals after doesn't count.
