Question

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 time?

Answer 1

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!
