Nora read 1/6 of a book on Monday and 2/5 on Tuesday. What fraction of the book does she have left to read?

Question

Answer and explain how you got the answer please

Answer 1

She read 1/6 of the book means that she read 5/30 of the book

She read 2/5 of the book means that she read 12/30 of the book

So in total she read 17/30 of the book.

The fraction for the entire book is 30/30. You can now compute what fraction of the book she has left.
