Nolan has read his sister the mermaid book 3 times out of every 5 times she picks a book. So, the mermaid book has been chosen 3 out of 5 times.
Out of 20 times Nolan has read his sister a book, he has read the mermaid book 3/5 x 20 = 12 times.
Therefore, Nolan has read the mermaid book 12 times this month.
Nolan reads his little sister one of her two favorite books each night before bed. This month, she has chosen the mermaid book 3 times for every 2 times she has chosen the princess book.
If Nolan has read his sister a book before bed 20 times this month, how many times has he read the mermaid book?
