Question

find the ratio of 4 litres to 450 ml

Answer 1

$$\begin{gathered} \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{litre}=1000\mathrm{ml} \\ \mathrm{So},4\mathrm{litres}=4000\mathrm{ml} \\ \mathrm{Ratio}\mathrm{of}4\mathrm{l}\mathrm{to}450\mathrm{ml}=\frac{4\mathrm{l}}{450\mathrm{ml}}=\frac{4000\mathrm{ml}}{450\mathrm{ml}}=\frac{4000}{450}=\frac{80}{9}=80:9 \end{gathered}$$
