Question

An oil drum has 15 kilo litres of oil in it how many tins of 3 litres would be filled from it?

Answer 1

$number \: of \: tins \: can \: be \: filled = \frac{volume \: of \: drum}{volume \: of \: one \: tin} \\ = \frac{15 {m}^{3} }{ \frac{3}{1000} {m}^{3} } \\ = \frac{15000}{3} \\ = 5000 \: tins$
