+/- 3/10
Restate the question: Solve for x: x2 = 9/100.
The rule to remember is that if x2=a, then x=+/- the square root ("sqrt") of a. +/- means that there are two solutions, a positive one and a negative one. (This is a little hard to explain without paper and pencil)
So in you question, x = +/- sqrt(9/100) = +/-sqrt(9)/sqrt(100) = +/- 3/10.

What is the answer for X over hundred equals 1 over 4?
X = 25 solves the problem x/100 = 1/4. To solve, multiple both sides by 100: now x = 100/4, and so x=25.

What is x squared over x squared?
Since x represents a single number, and it is x squared over x squared, then it will be the same numbers in the numerator and the denominator, no matter what value you replace x with (as long as you replace both x's with the same number). Therefore the answer is 1, unless the value of x is 0, in which case it is undefined. eg: 5 squared / 5 squared = 1 100 squared / 100 squared = 1 Try it with your calculator.
