I don't understand what you're doing now - your first step should be to write down an equation relating m and n; you can then substitute values into this.
You also need to quote me if you want me to see that you've replied!

Well, firstly TSR isn't a "do my homework" service, and secondly because I'm trying to help you learn so that you can do these problems independently. Otherwise you just end up with a list of answers to specific questions, not a general method.
Your posts have been a bit confused up to now - first you mentioned proportion, then square roots, then inverse proportion. So let's recap some rules:
if x is proportional to y, we can write: x=ky where k is a constant If x is inversely proportional to y, we can write x=yk where k is a constant If x is proportional to the square root of y, we can write x=ky where k is a constant.
Am I correct in thinking that your question says "n is inversely proportional to the square root of m"? In which case, what do you think the rule should look like in terms of n, m and constant k?
You are given two values of n and m that work together. These should help you find k. Once you have k, you can just plug another value of m (e.g. m = 100) into the rule to find the n that corresponds to that value of m.
If you're still stuck, you might want to make your teacher aware that you're struggling a bit with this topic. Have you done some worked examples in class or from a text book?
