Question

The ratio of rainbow butterflies to blue butterflies in the Exhibit is 3 to 4. There are 27 blue butterflies in the Exhibit. What is the total number of
butterflies in the Exhibit?

Answer 1

Answer:

There are 47 butterflies

Step-by-step explanation:

We can write a proportion of 3/4 = x/27 to find out how many rainbow butterflies there will be if there is 27 blue butterflies.

1. Cross Multiply 4x=81 = 20.25

Since you cannot have 20.25 butterflies you would round down to 20.

2. Add 20 to 27

Answer = 47

Answer 2

It is 36 butterflies because 3 x 9= 27 and whatever you do to one side you do the same so 4 x 9= 36
