Answer:
The value of the first "
" in the number 
is ten times that of the second "
" in this number.
Step-by-step explanation:
What gives the number "" its value? Of course, each of its six digits has contributed. However, their significance are not exactly the same. For example, changing the first 
to 
would give 
and increase the value of this number by 
. On the other hand, changing the second 
to 
would give 
, which is an increase of only 
compared to the original number.
The order of these two digits matter because the number "" is written using positional notation. In this notation, the position of each digits gives the digit a unique weight. For example, in 
:
.
(Note that the index starts at 
from the right-hand side.)
Using these weights, the value can be written as the sum:
.
As seen in this sum, the first "" contributed 
to the total value, while the second "" contributed only 
.
Hence: The value of the first "" in the number is ten times that of the second "" in this number.

Answer:
$32
Step-by-step explanation:
To find the commission, multiply the rate by the sales:
commission = 5% × $640 = $32
He made $32 in commission.

<em>Additional comment</em>
Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.
5% = 5/100 = 0.05 = 1/20
Then 5% × $640 = $640/20 = $64/2 = $32.
