Correct, although if the m and n stands for something (like say a meter, mile, nautical meter, nanometer) then you'd have to convert them to the same unit and then find the ratio.

maths in anime forum... hmmm... hehehe

[Kalectras]

and economics next be accounting but i hasn't have problem yet...

[danko]

all ur fault Kale-kun... bad... bad...

[Kalectras]

meh WHAT!! why my fault?

[danko]

blame u for everything

[liquidfreedom88]

well, thats good to hear that even watch anime vigourously, we still care for hw and stuffs . though right now i still dont have anything to ask...

and bout that 9m:5n,
if thats all the question, then its right, the ratio is 9:5
but if they ask the value of m and n, it'd need another pointer i believe.

Another math problem. I don't get it at all.
If triangles of x-long legs are cut off the corners of square JKLM, an octagon results. If the octagon is regular and a side is represented as s, find x in terms of s.
=\
I've only come up with the drawing so far.

regular octagon means all sides are equal... so *any* side of the octagon = s

if you can visualize it, since you say youve drawn the picture, the hypotenuse of the triangle is equal to one side of the octagon. as ive stated before, any side of the octagon = s. so s = the hypotenuse of the triangle.

so basically what you need to do is find what the hypotenuse of the triangle is with x-long legs. as a hint: if both legs are equal length, x, and that it is also cut from a corner of a square, then you know it is an right isosceles triangle... you can use pythagorean's theorem to quickly find the answer.
