Answer 1

Step 1: Express the bigger quantity in terms of the smaller quantity

$15\mathrm{kg}$ is bigger than $210\mathrm{g}$.

$$\begin{gathered} 1\mathrm{kg}=1000\mathrm{g} \\ \therefore 15\mathrm{kg}=15000\mathrm{g} \end{gathered}$$

Step 2: Compute their ratio

Ratio of $15\mathrm{kg}$ to $210\mathrm{g}$ is,

$$\begin{gathered} 15000:210 \\ =500:7 \end{gathered}$$

Therefore, ratio of $15\mathrm{kg}$ to $210\mathrm{g}$ is $500:7$.
