Re: Save Me From Failure

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?

Hi;

That's correct.

Re: Save Me From Failure

Not true. I am never annoyed at a question. I learn a lot from answering a question.

Next one:

Find the ratio of X to Y

X/3 = 5/8 = 5/Y the answer is Y = 8.

can we come back to this?

In confused because we are supposed to be finding the ratio between x and y...

so since you found Y how do i do the rest? Now i need to find X in order to find the ratio between the two right?

Re: Save Me From Failure

ok now i see i mistook a 3 for an 8

ok the real problem is:

Find the ratio of X to Y

X/3 = 5/3 = 5/Y

please forgive me that was a bone-head error

Re: Save Me From Failure

X is to 3 as 5 is to 3 : So X is 5

Then 5 is to 3 as 5 is to Y so Y is 3

Re: Save Me From Failure

Is that okay, misheeru? I can create a video if the solution is still unclear.

Re: Save Me From Failure

I like your vids devante however I am restricted to go to site like youtube on the school school computor.

X is to 3 as 5 is to 3 : So X is 5

Then 5 is to 3 as 5 is to Y so Y is 3

I  sorta see what you are sayin however my exercises are multiple choice and i need find out how to shorten that or write it differently to match their choices

Re: Save Me From Failure

well bobbym, I said I had two days... My test was taken today >_<

It was hard, ratios was not all it covered....

My mistake I should have posted sooner... I'll remember that next time

Scores come out in a few days usually, I'll let ya know

I'm starting a new unit now so i'll have new things to be bad at

If you do get your test back, tell me about any questions which you got wrong, and I'll post a video solution of them.
