To solve the equation \( x^2 = \frac{16}{25} \) by inspection, we can take the square root of both sides:
\[ x = \pm \sqrt{\frac{16}{25}} \]
Calculating the square root gives:
\[ x = \pm \frac{\sqrt{16}}{\sqrt{25}} = \pm \frac{4}{5} \]
Thus, the two real solutions are:
\[ \frac{-4}{5} \quad \text{and} \quad \frac{4}{5} \]
According to the instruction to enter the lesser number first, the final answers are:
\[ \frac{-4}{5}, \frac{4}{5} \]
