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 octal to binary like this:
11010101008 = 1 1 0 1 0 1 0 1 0 0 = 1(=001) 1(=001) 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 1(=001) 0(=000) 0(=000) = 0010010000010000010000010000002
answer: 11010101008 = 10010000010000010000010000002
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
1∙89+1∙88+0∙87+1∙86+0∙85+1∙84+0∙83+1∙82+0∙81+0∙80 = 1∙134217728+1∙16777216+0∙2097152+1∙262144+0∙32768+1∙4096+0∙512+1∙64+0∙8+0∙1 = 134217728+16777216+0+262144+0+4096+0+64+0+0 = 15126124810
got It: 11010101008 =15126124810
Translate the number 15126124810 в binary like this:
the Integer part of the number is divided by the base of the new number system:
