Question 4081
ok.. here we go... 

lets work this backwards... 1/3 two days in a row... so.... 1/3 + 1/3 = 2/3 right?  

Now we started with 3 1/2 and we ate 2/3 so.... there are a couple ways to work this but... i think we should change that 3 1/2 to an improper faction... 

3 1/2 (change to improper faction) is 7/2 (how?? 3 x 2 = 6 + 1 = 7 over 2) got it??  

now 7/2 - 2/3 (we need the same denomintor with fractions) so... think 6...

7/2 becomes 21/6 (how??  2 / 6 = 3 x 7 = 21) and 2/3 becomes 4/6 (how?? 3 / 6 = 2 x 2 = 4)

SO.... 21/6 - 4/6 = 17/6 (reduce the improper faction) (how?? 6 goes into 17 2 times (12) with 5 left over... put the 5 over 12)

the final answer is 2 5/6.  

Got it?
