Here is your pic, drawn to scale

the radius of the bigest circle is 7

the radius of the second biggest circle is 5

the radius of the little circles is 1

Now you can work out all the areas that are needed and find the fraction requested.

Here is the question

Start by getting a common denominator then I will help more.

This cannot be answered without the picture.

Nothing like good manners and graciousness. ... That is sarcasm.

Note: I would not bother responding more to you.

I don't know if it is right or wrong but thanks for your efforts Geno.

Thankyou 

Thanks,

You should also give the web address.

You have obviously copied this from somewhere guest. So it is plagiarised

IT is ok to show this BUT

You must cite there it comes from. e.g. give the link.

Thanks for brainstorming this with me guest.

I really enjoy interacting with other people here!    

Thanks guest,

I almost never remember combination formulas.  

They are great if you want to write programs to solve general situations but for me I am only usually interested in one off solutions so  I want to understand how to get the answer purely from my own logic. 

I will try and work out why this formula works. If I do then I will try to include the technique in my future one of problem solving.
