Convert the following rational numbers into the form of a terminating decimal or a non-terminating and repeating decimal, whichever the case may be, by the process of long division:

(A) $\frac{3}{50}$

(B) $\frac{2}{9}$

(A) $\frac{3}{50}: 50 = 2 \times 5^{2}$ (only 2s and 5s) $\rightarrow$ Terminates

$$\frac{3}{50} = \frac{6}{100} = 0.06$$

(B) $\frac{2}{9}: 9 = 3^2$ (contains 3) $\rightarrow$ Repeats

$$\frac{2}{9} = 0.2222... = 0.\overline{2}$$
