One way to do it would be: multiply your number by 100, then find the nearest 2 perfect squares and interpolate, then divide that number by 10 to get the approximate square root of the original number.
This works because if a = b2, where a is your original number and b would be the square root of that number.
Then multiply both sides by 100 {Note: 100 = 102}
100*a = 100*(b2) = (10²)*b² = (10*b)²
Lets say you want to find the square root of 5, so mult by 100 --> 500
What squares are close to 500? 22² = 484 and 23² = 529
484 is closer to 500 than 529: (529-500=29 & 500-484=16)
So 22² is closer to 500 than 23² & (2.2)² is closer to 5 than (2.3)²
So square root of 5 = 2.2 (to 1 decimal place)
Check your answer: 2.2 * 2.2 = 4.84

Find the square root to the thousandth place (3rd decimal digit) and round it to 2 decimal places to give the square root in hundredths. If you want a fraction, convert the decimal hundredths to a fraction by putting them over 100 and simplifying.
