Question

Find:
(i) 1.07 × 0.02
(ii) 211.9 × 1.13
(iii) 10.05 × 1.05
(iv) 13.01 × 5.01

Answer 1

i)
$$\begin{gathered} \frac{107}{100}\times \frac{2}{100} \\ =\frac{107\times 2}{10000} \end{gathered}$$
= 0.0214


ii)
$$\begin{gathered} \frac{2119}{10}\times \frac{113}{100} \\ =\frac{239447}{1000} \\ =239.447 \end{gathered}$$

iii)
$$\begin{gathered} \frac{1005}{100}\times \frac{105}{100} \\ =\frac{105525}{10000} \\ =10.5525 \end{gathered}$$

iv)

$$\begin{gathered} \frac{1301}{100}\times \frac{501}{100} \\ =\frac{651801}{10000} \\ =65.1801 \end{gathered}$$
