Wendy had a non-fiction book with 340 pages. She read 40% of the non-fiction book on Thursday, 40% of the non-fiction book on Friday and the rest on Saturday.
- How many pages did she read on Saturday?
- How many more pages did she read on Thursday than on Saturday?
(a)
100% → 340
1% → 340 ÷ 100 = 3.4
Number of pages that Wendy read on Saturday in percent
= 100% - 40% - 40%
= 20%
Number of pages that Wendy read on Saturday
= 20 x 3.4
= 68
(b)
Number of more pages that Wendy read on Thursday than on Saturday in percent
= 40% - 20%
= 20%
20% → 20 x 3.4 = 68
Number of more pages that Wendy read on Thursday than on Saturday = 68
Answer(s): (a) 68; (b) 68
