SOLUTION: Solve for p
1/p+1/q=1/f
I came up with the lcm:fpq so now it turns into this:
fq/fpq+fp/fpq=pq/fpq
But I don't know where to go from there. I saw someone else just do this:
fq

Question 265079: Solve for p
1/p+1/q=1/f
I came up with the lcm:fpq so now it turns into this:
fq/fpq+fp/fpq=pq/fpq
But I don't know where to go from there. I saw someone else just do this:
fq+fp=pq but it seemed confusing because I don't know what they did with the denominator Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Solve for p
the common denominator is pqf, multiply each term by pqf, this gets rid of the denominators, results:
qf + pf = pq
:
Subtract qf from both sides
pf = pq - qf
:
subtract pq from both sides
pf - pq = -qf
:
Factor out p on the right
p(f-q) = -qf
:
Divide both sides by (f-q), results
p =
:
Did this make sense to you now?
