Translate to :

This transfer is possible in two ways: direct transfer and using the decimal system.

first, let\'s make a direct transfer.

let\'s do a direct translation from hexadecimal to binary like this:

DCA_{16} = D C A = D_{(=1101)} C_{(=1100)} A_{(=1010)} = 110111001010_{2}

answer: DCA_{16} = 110111001010_{2}

now let\'s make the transfer using the decimal system.

let\'s translate to decimal like this:

13∙16^{2}+12∙16^{1}+10∙16^{0} = 13∙256+12∙16+10∙1 = 3328+192+10 = 3530_{10}

got It: DCA_{16} =3530_{10}

Translate the number 3530_{10} в binary like this:

the Integer part of the number is divided by the base of the new number system:

3530 | 2 | ||||||||||||

-3530 | 1765 | 2 | |||||||||||

0 | -1764 | 882 | 2 | ||||||||||

1 | -882 | 441 | 2 | ||||||||||

0 | -440 | 220 | 2 | ||||||||||

1 | -220 | 110 | 2 | ||||||||||

0 | -110 | 55 | 2 | ||||||||||

0 | -54 | 27 | 2 | ||||||||||

1 | -26 | 13 | 2 | ||||||||||

1 | -12 | 6 | 2 | ||||||||||

1 | -6 | 3 | 2 | ||||||||||

0 | -2 | 1 | |||||||||||

1 | |||||||||||||

the result of the conversion was:

3530_{10} = 110111001010_{2}

answer: DCA_{16} = 110111001010_{2}
