Question

$24$ milk cans contain $192$ litres of milk. How many such cans will be needed for $360$ litres of milk?

Answer 1

Given that

$24$ milk cans contain $192$ litres of milk

Let $x$ milk cans contain $360$ litres of milk

We have

$$\begin{gathered} 24:192=x:360 \\ 192x=360\times 24 \\ x=\frac{8640}{192} \\ x=45 \end{gathered}$$

Hence $45$ milk cans contain $360$ litres of milk.
