SOLUTION: After paying 1/mth and 1/nth of a bill, a remained as due.
Determine the bill amount.
My attempt:
Let x = amount of bill.
x - 1/m - 1/n = a
lcd = mn

Non-homework. Found 2 solutions by Edwin McCravy, josgarithmetic:Answer by Edwin McCravy(20054) (Show Source):
After paying "1/m"th and "1/n"th of a bill, "a" remained due.
Determine the bill amount.
My attempt:
Let x = amount of bill.
x - 1/m - 1/n = a <-- NO! Should be
lcd = mn <-- yes but multiply through by it, because
the idea is to CLEAR of fractions. Get
rid of them. Don't keep them!
xmn - 1/mn - 1/nm = amn <--No! Should be
which has NO fractions!
How do I continue ?
From this:
factor out x on the left:
Divide both sides by what's in the parentheses
