katie has red 32% of a book if she has to read 80 pages how many more pages does Katie have left to read
galben [10]
In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
                                                     = 256/10
                                                     = 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
                                                                               = 54.4 pages
So Katie has 54.4 pages left to read.
