Winnie had a guide book with 480 pages. She read 40% of the guide book on Friday, 25% 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% → 480
1% → 480 ÷ 100 = 4.8
Number of pages that Winnie read on Sunday in percent
= 100% - 40% - 25%
= 35%
Number of pages that Winnie read on Sunday
= 35 x 4.8
= 168
(b)
Number of more pages that Winnie read on Friday than on Sunday in percent
= 40% - 35%
= 5%
5% → 5 x 4.8 = 24
Number of more pages that Winnie read on Friday than on Sunday = 24
Answer(s): (a) 168; (b) 24
