A mixed apple vendor starts out with \(28 \frac{2}{5}\) apples, sells \(5 \frac{1}{2}\) apples to Bob, and then sells \(7 \frac{1}{3}\) apples to Jane. After these two sales, how many apples does the vendor have left (expressed as a mixed number)?

2/5  =  12/30

1/2  = 15/30

1/3  = 10/30.....so

 

28 2/5  -  5 1/2  =

28 12/30  - 5 15/30  =

27 42/30 - 5 15/30  =

22 27/30

 

And

 

22 27/30  - 7 10/30  =

 

15 17/30   apples left

 

cool cool cool
