- Solving a numerical problem without a calculator

I have to solve a certain numerical problem without using calculator and furthermore, there is a time limit for solving this problem.

The answer I have got so far is ## \sqrt{\frac{100}{99}}##

I know I can reduce the numerator to 10 but then I am stuck with square root of denominator which is not a perfect square.

**Question**: How would I determine in shortest possible time the above square root without any calculator or tables?
