Answer:
To solve for \( x \), you need to isolate it on one side of the equation.
Given the equation \( \frac{5}{2} \times x = 1 \), you can solve for \( x \) by dividing both sides of the equation by \( \frac{5}{2} \):
\[ x = \frac{1}{\frac{5}{2}} \]
Dividing by a fraction is the same as multiplying by its reciprocal:
\[ x = 1 \times \frac{2}{5} \]
\[ x = \frac{2}{5} \]
So, \( x = \frac{2}{5} \).
