Solution

i) On dividing by 100, we get:

4.74 $\times$ 10 = $\frac{474}{100} \times 10 = \frac{474}{10} = 47.4$

ii) On dividing by 100, we get:

$\frac{45}{100} \times 10 = \frac{45}{10} = 4.5$

iii) Because the decimal is after 4 places from the right, we will divide by 10,000. We get:

$\frac{215}{10000} \times 10 = \frac{215}{1000} = 0.215$

iv) Because the decimal is after 4 places from the right, we will divide by 10,000. We get:

$\frac{54}{10000} \times 10 = \frac{54}{1000} = 0.054$
