Question

3 1/3 - 2 2/5 what is the answer?

Answer 1

One way to solve this is by changing the mixed numbers to improper functions. 
3 1/3 = 10/3
2 2/5 = 12/5

The next step I would take is to find a common denominator.
10/3 = 50/15
12/5 = 36/15

Now we can solve the original equation: 
50/15 - 36/15 = 14/15

Since 14/15 is already simplified this is your final answer.
