Question

jen has read ⁴/5 of a book. the next day she read ⅔ of what she had left . what fraction of the book is left to read?

Answer 1

After Jen read 4/5 (12/15) of a book there was 1/5 left.
The next day she reads 2/3 of 1/5 which equals 2/15 of the book
So by 2 days 14/15 of the book is read and there is 1/15 left.

Answer 2

Jen read 4/5 of a book.....leaving 1/5 left to read
she then read 2/3 of what she had left.....2/3 of 1/5 =..." of " means multiply
2/3 * 1/5 = 2/15

5/5 - (4/5 + 2/15) =
5/5 - (12/15 + 2/15) =
5/5 - 14/15 =
15/15 - 14/15 =
1/15 <=== 1/15 of the book is left to read
