a ABC company stock dropped from 25 3/8 to 22 1/4 during a one month period of time so how much stock fall during this period of
OLEGan [10]
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):
25 \frac{3}{8} =  \frac{203}{8}
22 \frac{1}{4} =  \frac{89}{4}

Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:
2 (\frac{89}{4} ) =  \frac{178}{8}

Now that we have a common denominator, we are ready to subtract:
\frac{203}{8} -  \frac{178}{8} =  \frac{25}{8}

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:
3 \frac{1}{8}

And that's your answer: 3 \frac{1}{8}

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