What is the least common denominator of 388.5 and 518? Multiply that amount times each term. Add up and simplify. Try it out.I need to solve the equation (2 d)/(d/518+d/388.5)
I've also attached an image of it, which is clearer. I know the answer is 444, but I don't know how to reach it.
Can anyone help?

An exact answer can not be given because 388.5 is not exact.
d = whatever your little heart desires
Then, if coded in Basic, you get message: "division by 0"
Or code this way:
100 INPUT "enter d";d
110 IF d=0 THEN t=t+1
120 IF t<4 THEN PRINT "d cannot = 0; re-enter": GOTO 100
130 PRINT "go away, dummy!!" : END
I did state that the answer was 444, so it is an equation if you write it mathematically.
No, that does not follow logically. It is an expression, not an equation, and it simplifies to 444, provided d does not equal 0.
Anyway, srmichael had the answer - thank you. It is possible to solve for d,
There is no solving for any variable. There is no equation.
which is what I was asking, No, that is not your intent. Your intent is to have that *expression* simplified
(in this case to a constant).
if not very coherently.
