Tiffany had a novel with 190 pages. She read 40% of the novel on Monday, 40% of the novel on Tuesday and the rest on Wednesday.
- How many pages did she read on Wednesday?
- How many more pages did she read on Monday than on Wednesday?
(a)
100% → 190
1% → 190 ÷ 100 = 1.9
Number of pages that Tiffany read on Wednesday in percent
= 100% - 40% - 40%
= 20%
Number of pages that Tiffany read on Wednesday
= 20 x 1.9
= 38
(b)
Number of more pages that Tiffany read on Monday than on Wednesday in percent
= 40% - 20%
= 20%
20% → 20 x 1.9 = 38
Number of more pages that Tiffany read on Monday than on Wednesday = 38
Answer(s): (a) 38; (b) 38
