Blenda has 3 7/20 books of stamps and she only needs one stamp to mail her recipe newsletter (each book holds twenty stamps). How many newsletters can Blenda mail? Explain how you found your answer.

She needs 1 stamp per newsletter, so she can mail 67 newsletters.

67 newsletters

Step-by-step explanation:

Each book of stamps hold 20 stamps. She has 3 whole books and 7/20 of a book

3 whole books with 20 stamps in each = 3*20 = 60 stamps

7/20 of a book means 7/20 of a book. We multiply this fraction by the total number of stamps in a book

7/20 * 20 = 7 stamps

The total number of stamps in 3 7/20 books of stamps is found by adding the number of stamps in the whole books plus the number of stamps in the fractional bool

60+7 = 67 stamps

She needs 1 stamp per newsletter, so she can mail 67 newsletters.
