Linda had a non-fiction book with 220 pages. She read 50% of the non-fiction book on Thursday, 25% 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% → 220
1% → 220 ÷ 100 = 2.2
Number of pages that Linda read on Saturday in percent
= 100% - 50% - 25%
= 25%
Number of pages that Linda read on Saturday
= 25 x 2.2
= 55
(b)
Number of more pages that Linda read on Thursday than on Saturday in percent
= 50% - 25%
= 25%
25% → 25 x 2.2 = 55
Number of more pages that Linda read on Thursday than on Saturday = 55
Answer(s): (a) 55; (b) 55
