Hello!

<u><em>Answer: ⇒ 1/38</em></u>

Step-by-step explanation:

Convert element to fraction.

\frac{1}{2}\div \frac{19}{1}

Apply the fraction rule.

\frac{1}{2}*\frac{1}{19}

Then you can multiply by the fraction.

\frac{1*1}{2*19}

Multiply by the numbers.

1*1=1

\frac{1}{2*19}

=\frac{1}{38}

Hope this helps!
