Question

Express as kilogram using decimals: $5kg8g$

Answer 1

Express the given weight in kilograms

We know that, $1kg=1000g$

Given, $5kg8g$

Here we just need to convert $8g$ into kilograms.

Using unitary method, we get

$$\begin{gathered} \Rightarrow 1000g=1kg \\ \Rightarrow 1g=\frac{1}{1000}kg \\ \Rightarrow 8g=\frac{8}{1000}kg \\ \Rightarrow 8g=0.008kg \end{gathered}$$

Thus, $5kg8g$ can be written as $\left[5+0.008\right]kg=5.008kg$

Therefore, $5kg8g$ can be written as $5.008kg$.
