See explanation

Explanation:

Here is the complete question:

Sam read 2/5 of her book over the weekend, and 1/6 on monday, what fraccion of the book has she read? What fraccion of the book is left?

First we have to know the lowest common multiple of the denominator which is 5 and 6. Therefore, the LCM is 30.

The fraction of the book she has read will be:

= 2/5 + 1/6

= (2/5 × 30) + (1/6 × 30)

= 12/30 + 5/30

= 17/30

Tye fraction of the book left will be:

= 1 - 17/30

= 30/30 - 17/30

= 13/30
