It's 1010 You round the 10.25 down to 10, so it's the same as it would be for 10.
The binary number 10101010 is equivalent, in decimal representation, to 128 + 32 + 8 + 2 = 170. But this answer assumes that the given number is binary - an assumption for which there is no real justification. Besides, the relationship is an equivalence, which is not quite "the same thing".
It is the same number: 1. Binary numbers are base-2, with each digit place corresponding to an exponent of 2 rather than 10 in the decimal number system. So that the number 11, which in decimal means 10 + 1, would represent 2 + 1 (3) in the binary system, which can only have the value 0 or 1 in each digit place.
The same as real numbers are expressed in decimal, except only the digits 0 and 1 are used (instead of 0 to 9) and the separator between the integer and fraction part is called the binary point (instead of the decimal point). The sign if needed is the same as in decimal.
Write each decimal number to the same number of decimal places, by inserting suffix 'zeroes'. Hence ;- 1.001 , ; 1.100 ; 1.010 ; 1.011 Drop the decimal point 1001, 1100 , 1010 , 1011 Hence from smallest to largest 1001 < 1010 < 1011 < 1100 In words, 'One thousand and one' is less than ' one thousand and ten' , is ;less than 'one thousand and eleven' , is less than 'one thousand one hundred'. Hence it follows. 1.001 < 1.01 < 1.011 < 1.1
