Diana had a textbook with 150 pages. She read 50% of the textbook on Tuesday, 5% of the textbook on Wednesday and the rest on Thursday.
- How many pages did she read on Thursday?
- How many more pages did she read on Tuesday than on Thursday?
(a)
100% → 150
1% → 150 ÷ 100 = 1.5
Number of pages that Diana read on Thursday in percent
= 100% - 50% - 5%
= 45%
Number of pages that Diana read on Thursday
= 45 x 1.5
= 67.5
(b)
Number of more pages that Diana read on Tuesday than on Thursday in percent
= 50% - 45%
= 5%
5% → 5 x 1.5 = 7.5
Number of more pages that Diana read on Tuesday than on Thursday = 7.5
Answer(s): (a) 67.5; (b) 7.5
