In the last hour, Ellie observed 32 monarchs, 56 gulf fritillaries and 8 giant swallowtails visit her butterfly garden. If 480 butterflies visit her garden, how many can we expect will be giant swallowtails?

Answer:

40 giant swallowtails

Computation:

Simplifying the given ratio of butterflies in Ellies garden.

\left\begin{array}{ccc}monarchs:&giant\:fritillaries:&giant\:swallowtails\\32&56&8\\4&7&1\end{array}\right

Summing up the parts of the simplified ratio.

4+7+1=12

Solving for the value per part when 480 butterflies visit Ellies garden.

480/12=\boxed{40}\\\\As\:the\:ratio\:of\:giant\:swallowtails\:is\:1\:part,\\\:this\:is\:also\:the\:number\:we\:can\:expect\:\\when\:480\:butterflies\:visit\:Ellies\:garden.
