To find the product of \(\sqrt{12}\) and \(\frac{5}{6}\), we will first calculate \(\sqrt{12}\):
\[ \sqrt{12} = \sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2\sqrt{3} \]
Now, we will multiply this by \(\frac{5}{6}\):
\[ 2\sqrt{3} \times \frac{5}{6} = \frac{10\sqrt{3}}{6} = \frac{5\sqrt{3}}{3} \]
Now, we need to evaluate \(\frac{5\sqrt{3}}{3}\) numerically. To do this, we can approximate \(\sqrt{3}\):
\[ \sqrt{3} \approx 1.732 \]
Thus,
\[ \frac{5\sqrt{3}}{3} \approx \frac{5 \times 1.732}{3} \approx \frac{8.66}{3} \approx 2.8867 \]
The result is approximately \(2.8867\), and since \(\sqrt{3}\) is an irrational number, the product \(\frac{5\sqrt{3}}{3}\) is also an irrational number.
So, the final answer is:
A) 2.8867 . . . ; an irrational number
