To answer this we need to get the same denominator for each. So we need to find a LCD. I think 30.
Then we change them all to have a denominator of 30
1/6=5/30
2/5=12/30
1/3=10/30
Add it up 10+12+5=27
so 27/30
But than can be simplified
Divide by 3 on the top and bottom
9/10
She has read 9/10 of her book
Hope this helps! :)
