Question

A marine biologist would like to feed some dolphins a mix of fish that consists of 8parts cod to 7 parts mackerel. List a combination that would be an acceptable mixture of these fish

Answer 1

SOLUTION

From the question, we can see that this is a ratio. The biologist wants to make a feed that contains cod and mackerel in the ratio of 8 : 7, that is 8 parts of cod and 7 parts of mackerel.

An acceptable mixture of this is also

$\begin{gathered} 8\times3\text{ parts of cod }=\text{ 24 parts of cod } \\ 7\times3\text{ parts of mackerel }=\text{ 21 parts of mackerel} \end{gathered}$

Hence an acceptable mixture of this is 24 parts of cod and 21 parts of mackerel.
