To find the product of the two rational numbers \(36\) and \(\frac{5}{3}\), we calculate:
\[ 36 \times \frac{5}{3} = \frac{36 \times 5}{3} = \frac{180}{3} = 60 \]
Since \(60\) can be expressed as a fraction \(\frac{60}{1}\), it is a rational number. A number is rational if it can be expressed as a fraction where both the numerator and the denominator are integers, so the product of two rational numbers is always rational.
