Answer:
8/5 or 1 3/5
Step-by-step explanation:
2 2/5 = 12/5
1 1/2 = 3/2 
Now that we have fractions that are easier to divide, one must understand that the opposite of dividing is multiplying. So if you multiply 12/5 by the reciprocal* of 3/2, which would be 2/3, you would get your answer so...
12     3         12    2        24     8             3
—  ÷ —   =    — × —    =  —  = —   <em>or</em>  1  —
5       2         5     3        15      5             5 
*the reciprocal is the opposite of the fraction you have. So the denominator would become the numerator, and vise versa.
