Question

In the Butterfly Museum, there are only pink and yellow butterflies. The ratio of the number of pink butterflies to the number of yellow butterflies is 3:5. If there are 18 pink butterflies, how many butterflies are there altogether?

Answer 1

Answer:  There are 48 butterflies altogether.

Step-by-step explanation:

Since we have given that

The ratio of number of pink butterflies to the number of yellow butterflies is 3:5

So,

Let the number of pink butterflies be 3x

Let the number of yellow butterflies be 5x

As we have given that there are 18 pink butterflies,

So,

$3x=18\\\\x=\frac{18}{3}\\\\x=6$

So, total number of butterflies is given by

$5x+3x=8x\\\\8x=8\times 6=48$

Hence, there are 48 butterflies altogether.
