Marion had a novel with 170 pages. She read 35% of the novel on Wednesday, 35% of the novel 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% → 170
1% → 170 ÷ 100 = 1.7
Number of pages that Marion read on Friday in percent
= 100% - 35% - 35%
= 30%
Number of pages that Marion read on Friday
= 30 x 1.7
= 51
(b)
Number of more pages that Marion read on Wednesday than on Friday in percent
= 35% - 30%
= 5%
5% → 5 x 1.7 = 8.5
Number of more pages that Marion read on Wednesday than on Friday = 8.5
Answer(s): (a) 51; (b) 8.5
