Gillian had a fiction book with 240 pages. She read 40% of the fiction book on Wednesday, 40% of the 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% → 240
1% → 240 ÷ 100 = 2.4
Number of pages that Gillian read on Friday in percent
= 100% - 40% - 40%
= 20%
Number of pages that Gillian read on Friday
= 20 x 2.4
= 48
(b)
Number of more pages that Gillian read on Wednesday than on Friday in percent
= 40% - 20%
= 20%
20% → 20 x 2.4 = 48
Number of more pages that Gillian read on Wednesday than on Friday = 48
Answer(s): (a) 48; (b) 48
