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):
[tex]25 \frac{3}{8} = \frac{203}{8} [/tex]
[tex]22 \frac{1}{4} = \frac{89}{4} [/tex]
Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:
[tex]2 (\frac{89}{4} ) = \frac{178}{8} [/tex]
Now that we have a common denominator, we are ready to subtract:
[tex] \frac{203}{8} - \frac{178}{8} = \frac{25}{8} [/tex]
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:
[tex]3 \frac{1}{8} [/tex]
And that's your answer: [tex]3 \frac{1}{8} [/tex]
Hope this all makes sense. If anything doesn't, feel free to tell me!
