Your answer :
47310 =  6318 17110 =  2538 98910 =  1, 7358  This set contains a mistake.
You are correct. 47310 = 7318 not 6318.
Very well, you now know how to convert decimal whole numbers to octal numbers by repeated division by 8. You previously learned to convert octal whole numbers to decimal by writing the number in expanded form and then doing the necessary arithmetic. For example,
368  = 3(81) + 6(80)  = 3(8) + 6(1)  = 2410 + 610 = 3010.
You are familiar with this process, having worked out a number of examples some pages back. Now, are the actual numerals written on the right of the equal (=) sign in the expansion above intended to be read as octal or as decimal numbers?
