Question

lashonda has 100 books. 25/100 are mysteries, 3/10 are adventure stories, and 45/100 are novels. what part of her books are mysteries or adventure stories? determine if there is extra or missing information.

Answer 1

Total number of books=100 books
number of Mysteries books=25/100*100=25 books
number of adventure stories=3/10*100=30
novels=45/100*100=45

Total number of accounted books:
25+30+45=100
From this information there are no lost books because the total number of books is equal to the number accounted for by the fractions.
