Question 168189: P+7/2=-5/4
Answer by checkley77(12844)   (Show Source):
You can put this solution on YOUR website! P+7/2=-5/4
P=-5/4-7/2 [find a common denominator which is 4)
P=(-5-7*2)/4
P=(-5-14)/4
P=-19/4 ANS.
-----------------------------
Proof:
-19/4+7/2=-5/4
-19/4++14/4=-5/4
-5/4=-5/4
-------------------------------
Thank you checkley77. I really appreciate the break down that you gave me. I just have one concern. If the answer is -19/4 and you put that into the equation as -19/4+7/2 wouldn't that equal -12/6? I am still a little confused. The answer I got for P was -12/2 but I wasn't sure that I had the correct formula.
-12/2+7/2=-5/4
-5/2 does not = -5/4
I believe you are confused about the denominators of 2 & 4.
In order to combine these fractions they have to have the same denominator.
Hpe this helps.
