Question

Which is greater?

$0.3\mathrm{or}0.4$

Answer 1

Determine the greater number.

As,

$$\begin{gathered} 0.3=\frac{3}{10} \\ 0.4=\frac{4}{10} \end{gathered}$$

And,

$$\begin{gathered} 3<4 \\ \Rightarrow \frac{3}{10}<\frac{4}{10} \\ \therefore 0.3<0.4 \end{gathered}$$

Hence, $0.4$ is greater than $0.3$
