Esther had a story book with 230 pages. She read 50% of the story book on Tuesday, 20% of the story 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% → 230
1% → 230 ÷ 100 = 2.3
Number of pages that Esther read on Thursday in percent
= 100% - 50% - 20%
= 30%
Number of pages that Esther read on Thursday
= 30 x 2.3
= 69
(b)
Number of more pages that Esther read on Tuesday than on Thursday in percent
= 50% - 30%
= 20%
20% → 20 x 2.3 = 46
Number of more pages that Esther read on Tuesday than on Thursday = 46
Answer(s): (a) 69; (b) 46
