To find the value of the expression [tex]\(\frac{x y^2}{5}\)[/tex] given [tex]\(x = 2\)[/tex] and [tex]\(y = 1\)[/tex], follow these steps:

1. Substitute the values of [tex]\(x\)[/tex] and [tex]\(y\)[/tex] into the expression:
[tex]\[ \frac{2 \cdot 1^2}{5} \][/tex]

2. Calculate the exponentiation part first, which is [tex]\(y^2\)[/tex]:
[tex]\[ 1^2 = 1 \][/tex]

3. Now multiply [tex]\(x\)[/tex] by the result of [tex]\(y^2\)[/tex]:
[tex]\[ 2 \cdot 1 = 2 \][/tex]

4. Finally, divide the result by 5:
[tex]\[ \frac{2}{5} = 0.4 \][/tex]

Therefore, the value of the expression is [tex]\(\boxed{0.4}\)[/tex].
