Cathy had a non-fiction book with 310 pages. She read 50% of the non-fiction book on Monday, 25% of the non-fiction book on Tuesday and the rest on Wednesday.
- How many pages did she read on Wednesday?
- How many more pages did she read on Monday than on Wednesday?
(a)
100% → 310
1% → 310 ÷ 100 = 3.1
Number of pages that Cathy read on Wednesday in percent
= 100% - 50% - 25%
= 25%
Number of pages that Cathy read on Wednesday
= 25 x 3.1
= 77.5
(b)
Number of more pages that Cathy read on Monday than on Wednesday in percent
= 50% - 25%
= 25%
25% → 25 x 3.1 = 77.5
Number of more pages that Cathy read on Monday than on Wednesday = 77.5
Answer(s): (a) 77.5; (b) 77.5
