Yoko had a fiction book with 280 pages. She read 50% of the fiction book on Friday, 30% of the fiction 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% → 280
1% → 280 ÷ 100 = 2.8
Number of pages that Yoko read on Sunday in percent
= 100% - 50% - 30%
= 20%
Number of pages that Yoko read on Sunday
= 20 x 2.8
= 56
(b)
Number of more pages that Yoko read on Friday than on Sunday in percent
= 50% - 20%
= 30%
30% → 30 x 2.8 = 84
Number of more pages that Yoko read on Friday than on Sunday = 84
Answer(s): (a) 56; (b) 84
