First, let's convert the mixed fraction into an improper fraction (trust me, mixed fraction are pretty much the worst things to deal with, especially with higher level math):


Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:

Now that we have a common denominator, we are ready to subtract:

Since that's the most simplified form, and you have been asked the question in a mixed fraction form, let's convert that to a mixed fraction. The remainder of the numerator divided by the denominator is 1, and the quotient is 3. The denominator stays the same. So, this is what results:

And that's your answer:

Hope this all makes sense. If anything doesn't, feel free to tell me!
