Wendy had a story book with 220 pages. She read 50% of the story book on Friday, 10% of the story 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% → 220
1% → 220 ÷ 100 = 2.2
Number of pages that Wendy read on Sunday in percent
= 100% - 50% - 10%
= 40%
Number of pages that Wendy read on Sunday
= 40 x 2.2
= 88
(b)
Number of more pages that Wendy read on Friday than on Sunday in percent
= 50% - 40%
= 10%
10% → 10 x 2.2 = 22
Number of more pages that Wendy read on Friday than on Sunday = 22
Answer(s): (a) 88; (b) 22
