Question

Divide:
(i) 0.45 by 9
(ii) 217.44 by 18
(iii) 319.2 by 2.28
(iv) 40.32 by 9.6
(v) 0.765 by 0.9
(vi) 0.768 by 1.6

Answer 1

(i)
$$\begin{gathered} \frac{0.45}{9}=\frac{45}{9\times 100} \\ =\frac{5}{100} \\ =0.05 \end{gathered}$$

(ii)
$$\begin{gathered} \frac{217.44}{18}=\frac{21744}{18\times 100} \\ =12.08 \end{gathered}$$

(iii)
$$\begin{gathered} \frac{319.2}{2.28}=\frac{3192\times 100}{228\times 10} \\ =140 \end{gathered}$$

(iv)
$$\begin{gathered} \frac{40.32}{9.6}=\frac{4032\times 10}{96\times 100} \\ =4.2 \end{gathered}$$

(v)
$$\begin{gathered} \frac{0.765}{0.9}=\frac{765\times 10}{9\times 1000} \\ =\frac{7650}{9000} \\ =0.85 \end{gathered}$$

(vi)
$$\begin{gathered} \frac{0.768}{1.6}=\frac{768\times 10}{16\times 1000} \\ =\frac{7680}{16000} \\ =0.48 \end{gathered}$$
