Julie had a story book with 440 pages. She read 40% of the story book on Wednesday, 35% of the story 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% → 440
1% → 440 ÷ 100 = 4.4
Number of pages that Julie read on Friday in percent
= 100% - 40% - 35%
= 25%
Number of pages that Julie read on Friday
= 25 x 4.4
= 110
(b)
Number of more pages that Julie read on Wednesday than on Friday in percent
= 40% - 25%
= 15%
15% → 15 x 4.4 = 66
Number of more pages that Julie read on Wednesday than on Friday = 66
Answer(s): (a) 110; (b) 66
