Mary has to read 2 books for school. Mary read 5/8 of the first book on Friday, and 3/8 of the second book on Saturday. The first book has 420 pages. What total fraction of these two books has Mary read?
+2668 \({{{5 \over 8 } + {3 \over 8} } \over 2} = {1 \over 2}\)
This means that Mary read \(1 \over 2\)of the two books.
