* 0. 4 5

_________

1 6 . 1 5

1 29 . 2 0

0 0 0. 0 0

________

1 4 5. 3 5

________

We shall then move the decimal point 2 places to the left.

Hence, we have

1.4535

To check (question 6), we divide our result obtained in question 5 by 3.23

$\frac{1.4535}{3.23}$$\begin{gathered} \frac{1.4535}{3.23}=\text{ }\frac{14535}{10000}\text{ }\frac{.}{.}\text{ }\frac{323}{100} \\ \\ \frac{14535}{10000}\text{ }\times\text{ }\frac{100}{323} \\ \\ \frac{14535}{32300}\text{ = }\frac{14535\text{ / 5}}{32300\text{ / 5}}\text{ = }\frac{2907}{6460}=\text{ }\frac{2907\text{ / 323}}{6460\text{ / 323}}\text{ = }\frac{9}{20}=\text{ 0.45} \\ \\ \text{ } \end{gathered}$
