Find the difference 9 1/3 - 2/3
olga2289 [7]
Answer:  9 1/3 - 2/3 =  8  2/3 .
___________________________________

Note:  If the answer were "8 1/3" ; 

then:  "8 1/3 + 2/3 =? 9 1/3 ? "  

      → "8 1/3 + 2/3 = 8  3/3 = 8 + 1 = 9 = only "9" ;
____________________________________________
So the answer has to be MORE than "8 1/3"

Try "8 2/3"  → "8 2/3 + 2/3 =? 9 1/3?" ?? ; 
        
                  → "8 2/3 + 2/3 = 8 4/3 = 8 + 1 1/3 = 9 1/3 " → Yes!
_________________________________________________
 So, the answer is:  "8  2/3" .
_________________________________________________
Another method:
_________________
Given the problem:  "<span>9 1/3 - 2/3 " ;
___________________________________
Note that:  "2/3 = 1/3 + 1/3"
__________________________________
So, "</span><span>9 1/3 - 2/3 = 9 1/3 - (1/3 + 1/3) = 9 1/3 - 1/3 - 1/3 = ?
 ________________________________________________
   Start with:  "</span>9 1/3 - 2/3" = 9.  Then 9 - 1/3 = 8 3/3 - 1/3 = 8 2/3.
<span>______________________________________________________
</span>Another method:
____________________________
Given the problem:  
____________________________
  "9 1/3 - 2/3 = ?? " ;
____________________________
  Convert "9 1/3" into "28/3" ;  ("3*9 = 27"); ("27+1=28");
                                           (The "3" comes from the "3" in the: "1/3" portion.)
_________________________________________________________
  So, we rewrite as:  
_____________________________________
   28/3 - 2/3 = (28 - 2) / 3 = 26/3 ; or, 8  2/3 .

vampirchik [111]
The stock price per share was $8.60
Number of shares bought 1000
Total price for the shares:
(Cost per share)*(Number of shares)
=8.60*1000
=$8600

The stock price after 1 year $9.15
Total number of shares is 1000
Current price=(current share price)*(number of shares)
9.15*1000
=$9150
current value=(Current price)-(buying price)
=9150-8600
=$550

Net Profit=(Current value)-(Expenses)
=550-14
=$536

Grant needs 2/3 cup of raisins and 3/4 cup of almonds to make trail mix, which statement can be used to find out if their are mo
mina [271]
To solve this problem, you must find a common denominator. First, you multiply the denominators together, then, multiply the numerator of the first fraction by the original denominator of the second fraction and vis-versa. 

3*4 = denominator of both
2*4 = numerator of first fraction
3*3 = numerator of second fraction

Your fractions should end up being 8/12 cups of raisins and 9/12 cup of almonds. You can now compare these fractions. 

Overall, there are 1/12 more almonds than raisins.
