Fuzzy brain needs some refresher help

[Dark Alchemist]

Hello,

I have 2 fractions like so h/18 and h/6 that involves addition but I would like to simplify that to be only one fraction but I am unsure how. I know how if the numerator was not an unknown but with an unknown (h in this case) I just don't know.

h is height and the first line away is height divided by 18 and the next line is height divided by 6 away from the previous line. Is there anyway to get a fraction to represent that last line as height divided by x so we can remove that first line?

Thank you.

I cannot understand the problem. Can you take a screen shot of your problem and post it here....

I know how [to add fractions] if the numerator was not an unknown

Then treat the symbol h as though it were some number. The process is the same.

For example, if you need to multiply h/6 by 3/3 in order to get a common denominator with something, then you multiply the numerator by 3 like this: 3h and the denominator by 3 like this 3*6.

h is height and the first line away is height divided by 18 and the next line is height divided by 6 away from the previous line. Is there anyway to get a fraction to represent that last line as height divided by x so we can remove that first line?

The red parts below are questions that occurred to me, as I read the first sentence above.

h is height of what and the first line away from what, and in what direction is height of what divided by 18 is this some slope h/18 and the next line is height of what divided by 6 another slope away from in what direction the previous line.

I'm sorry, but I also do not understand how to "get a fraction to represent [a] line" or how "divided by x … can remove [a] line" :-(
