Answer:

Figure show demonstration of $\frac{1}{6}$ and $\frac{1}{30}$

Step-by-step explanation:

Let chosen fraction be $\frac{1}{6}$

Now we multiply fraction with $\frac{1}{5}$

Result will be

= $\frac{1}{6}\times\frac{1}{5}$

= $\frac{1}{30}$

Figure show demonstration of $\frac{1}{6}$ and $\frac{1}{30}$
