So I'll start with the mixed number to improper fraction. 
Step one - multiply the denominator and the whole number.
Step two- take your product and add it to the numerator 
Step three- the sum is the numerator of the mixed number and the original denominator is the denominator 
___________________________
Now for improper fraction to mixed number 
Step one- see how many times the denominator goes into the numerator (ex. 2 goes into 9, 4 times With one left over) 
Step two -the 4 becomes the whole number and the 1 the numerator
Step three- use the same denominator
