The ratio of monarch butterflies to queen butterflies at a butterfly farm was 5: 2. if there are no additional butterflies at the farm, what is the ratio of queen butterflies to the total number of butterflies at the farm?

So we know if there are 5 groups/dozens of Monarch butterflies, there are 2 groups/dozens of Queen butterflies. In other words, there are 5 Monarch butterflies for every 2 Queen butterflies.

Then we can turn that into an equation.


From the last equation we wrote we can see that the total number of butterflies in the farm is .

When we compare the Queen butterflies to total butterflies, we get

The ratio of Queen butterflies to total butterflies is 2:7.

Ithink the correct answer is d.
