Jane had a non-fiction book with 230 pages. She read 50% of the non-fiction book on Wednesday, 5% of the non-fiction book on Thursday and the rest on Friday.
- How many pages did she read on Friday?
- How many more pages did she read on Wednesday than on Friday?
(a)
100% → 230
1% → 230 ÷ 100 = 2.3
Number of pages that Jane read on Friday in percent
= 100% - 50% - 5%
= 45%
Number of pages that Jane read on Friday
= 45 x 2.3
= 103.5
(b)
Number of more pages that Jane read on Wednesday than on Friday in percent
= 50% - 45%
= 5%
5% → 5 x 2.3 = 11.5
Number of more pages that Jane read on Wednesday than on Friday = 11.5
Answer(s): (a) 103.5; (b) 11.5
