A unit of land measurement in Babylon was called "gan" and equaled $1 \varepsilon 00$ shars.

Express in shars:

$$
\begin{aligned}
& 1) \left.\frac{1}{3} \text{ gan }+\frac{2}{18} \text{ gan; } \right. \\
& 2) \frac{1}{3} \text{ gan }+\frac{3}{18} \text{ gan; } \\
& 3) 1 \text{ gan }-\frac{1}{36} \text{ gan; }
\end{aligned}
$$

4) In the difference $20$ gan - $\left(1 \text{ gan } + \frac{1}{3} \text{ gan }\right)$, express the whole part in gans, the fractional part in shars.
