Math Is Fun Forum

Oh really, I was expecting more of an arguement

Its all good, I have an 11 year old sister so getting bossed around by tweens ticks me off a little.

Its ok though

waite don't do that i need to go back and look at the problems i think i made an error when i copied then down.....

ok so if we have this:

One polygon has a side of length 3 feet. A similar polygon has a corresponding side of length 9 feet. The ratio of the perimeter of the smaller polygon to the larger is_____

You dont change the units because they are the same so it is 3 to 9 correct? Which is simplified is 1/3 right?

ok so what about this one:

Find the Ratio in simplest form:

2/3 to 3/2

ok so for exapmle if it was say X/2 = 6/2

then it would be like X * 2 = 2 * 6?

Which then, assuming I have the 1st part right goes to  2 * 6 = 2X?  which goes to 12 = 2X? Then X = 6?

ok thats good ialways felt bad because when i would do tutoring , i felt like i was annoying my teachers..
like there mouth says"oh its good yourtrying to get help" but there eyes say"jeez this girl is dense, when is it gonna B 5:30?"

mine is the black and green one idk wut its called... i wonder if they have something in purple....

ok so if the units are different you need to change it got it

so wut about the other ones i have up here?
the

Find the ratio of X to Y

X/3 = 5/8 = 5/Y?

ok so theres 100 pennies in each dollar

so i would cange to.... 125 pennies to 800 pennies? But then i think it goes to 6.4... that isn't write is it?

hmmm ok so  for example if it was 30 to 6 would the answer be 5/1?

But if it was 30 minute to 6 hours it would be something like 30 mins to 360 mins or  1/12... or something like that?

By units you mean the hours and the minute right?
So then if is had just been 15 to 2 would it be the same?

Ok my first one is ratios:

I think I get the basic stuff like if it say here to "find the Ratio in simplest form"
and they give me: Fifteen minutes to Two hours" then the answer is just 15/2, right?

That was a guess
However I have no clue with this other stuff so here it is:

Find the Ratio in simplest form:

2/3 to 3/2

Next is this:

Find the ratio of X to Y

X/3 = 5/8 = 5/Y

and

Solve for X

3:12 = X:16

and

X/5 = 2/3

P.S. these exersises are multiple choice so if anyone wants the choices i can post those too, unless you prefer it this way

Ah a fellow brunette.

I actually dont no my hair is so dark its about one shade short of black.....

Maybe thats because my black dye faded?

Thats joke was a lie some red-heads are real hotties....

Take Haley Williams for example.. but wait her was dyed that color... oh no was she blonde to begin with??
