I have 3/5n - 4/5 = 1/5n

so what I did was gathered like terms first.... which means I carried 1/5n from the other side over and subtracting it to 3/5n

2/5n - 4/5 =

now I carry -4/5 over to the other side like this

2/5n = 4/5 and I know to find n I would have to divide 4/5 by 2/5 so I set up my fractions keeping note of making 4/5 into it's recipacle of 5/4

2/5 x 5/4 = 10/20 reduced equals 1/2 What is I'm doing wrong???

Its a multiple choice question to so here are the options

**n = -1 **

**n = 2 **

**n = 5/3 **

**n= 5/2**

You are turning the wrong fraction upside down :)

3/5n - 4/5 = 1/5n

I'll show you very formally.

The equation must always balance, like a tetter totter (I think that is what Americans call them)

**Whatever you do to one side you must do to the other side as well!**

\(\frac{3}{5}n-\frac{4}{5}=\frac{1}{5}n\\~\\ \frac{3}{5}n-\frac{4}{5}-\frac{1}{5}n=\frac{1}{5}n-\frac{1}{5}n\\~\\ \frac{2}{5}n-\frac{4}{5}+\frac{4}{5}=0+\frac{4}{5}\\~\\ \frac{2}{5}n=\frac{4}{5}\\~\\ \frac{2}{5}n\div \frac{2}{5} =\frac{4}{5}\div \frac{2}{5}\\~\\ n=\frac{4}{5}\div \frac{2}{5}\\~\\ n=\frac{4}{5}\times \color{blue}{\frac{5}{2}}\\~\\ n=\frac{2}{1}\\~\\ n=2\)

OOOOH thank you this really means alot to me I must have forgot about that rule well now I know were to correct myself thanks so musch by the way how to get thaty fancy faded out grey type and type in fractions I have always been curious on how to do it.

Melody, a teeter-totter is a two-seated ride that swings back and forth

A see-saw is a board that pivots in the center with a rider on each end

Well frankly for younger children they call it a teeter totter just to be cute other than that I don't know. although I don't know what you put there because of parental coontrols (Which isn't a problem) but I am thinking its a younger child show....... It could not be but I might.

ok thanks.

Maybe when I was young you called it a Teeter totter more but now it is changing so that See Saw is more common,

Here in Australia, it has always been a See Saw.

That was just an American you tube clip which definitely called it a Teeter Totter.

anyway, this is what I am talking about.

Hi Melody. I'm in the US. The video you provided showed what I mean by see-saw. I tried to find a pic/video of what I call a teeter-totter but was unable to.... everything showed a see-saw! There is a children's ride that we called a teeter-totter, but now I'm supposing the name was local to southeast Oklahoma, where I was at the time. I guess.

The ride is similar to a see-saw in that it is a horizontal plank with a seat at each end where the riders face each other. But rather than pivoting rotationally in the center, the plank swings back and forth from an overhead pivot, held by two stiff tubes that attach to the plank, making roughly a triangular shape. I'll keep looking for a pic.

Ok you call it a see saw but the people in the video called it a Teeter Totter.

Anyway, it doesn't matter. We all know what I was talking about (I hope lol)
