Explanation:

Step1: Cross - multiply

For a proportion \(\frac{a}{b}=\frac{c}{d}\), we check if \(a\times d = b\times c\). Here \(a = 3\), \(b = 5\), \(c = 8\), \(d = 25\). So we calculate \(3\times25\) and \(5\times8\).
\(3\times25=75\) and \(5\times8 = 40\).

Step2: Compare the products

Since \(75
eq40\) (i.e., \(3\times25
eq5\times8\)).

Answer:

No, the equation is not a proportion.
