Roshel had a guide book with 490 pages. She read 35% of the guide book on Tuesday, 35% of the guide book on Wednesday and the rest on Thursday.
- How many pages did she read on Thursday?
- How many more pages did she read on Tuesday than on Thursday?
(a)
100% → 490
1% → 490 ÷ 100 = 4.9
Number of pages that Roshel read on Thursday in percent
= 100% - 35% - 35%
= 30%
Number of pages that Roshel read on Thursday
= 30 x 4.9
= 147
(b)
Number of more pages that Roshel read on Tuesday than on Thursday in percent
= 35% - 30%
= 5%
5% → 5 x 4.9 = 24.5
Number of more pages that Roshel read on Tuesday than on Thursday = 24.5
Answer(s): (a) 147; (b) 24.5
