Gillian had a guide book with 290 pages. She read 35% of the guide book on Friday, 40% of the guide book on Saturday and the rest on Sunday.
- How many pages did she read on Sunday?
- How many more pages did she read on Friday than on Sunday?
(a)
100% → 290
1% → 290 ÷ 100 = 2.9
Number of pages that Gillian read on Sunday in percent
= 100% - 35% - 40%
= 25%
Number of pages that Gillian read on Sunday
= 25 x 2.9
= 72.5
(b)
Number of more pages that Gillian read on Friday than on Sunday in percent
= 35% - 25%
= 10%
10% → 10 x 2.9 = 29
Number of more pages that Gillian read on Friday than on Sunday = 29
Answer(s): (a) 72.5; (b) 29
