### Instruction: If $x$ is a number between 0 and 1, which of the following represents the smallest value?

A). $x$
B). $x^2$
C). $2x$
D). $\sqrt{x}$
E). $\frac{1}{x}$

Express your answer as A, B, C, D, or E.### Response: I think we should start by plugging in a number for x.
Yes, I agree. Let's try 0.5.
If x is 0.5, then the choices are 0.5, 0.25, 1, 0.71, and 2.
And out of those numbers, 0.25 is the smallest.
That corresponds to option B.
