To determine the product of \( \frac{3}{5} \) and \( 3\pi \), we can multiply them:
\[ \frac{3}{5} \times 3\pi = \frac{3 \times 3\pi}{5} = \frac{9\pi}{5} \]
Here, \( \pi \) (pi) is an irrational number, and multiplying an irrational number by a rational number (like \( \frac{9}{5} \)) results in an irrational number. Therefore, the product \( \frac{9\pi}{5} \) is also an irrational number.
So the type of product you will get from multiplying \( \frac{3}{5} \) and \( 3\pi \) is irrational.
