Abi had a story book with 180 pages. She read 40% of the story book on Tuesday, 25% 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% → 180
1% → 180 ÷ 100 = 1.8
Number of pages that Abi read on Thursday in percent
= 100% - 40% - 25%
= 35%
Number of pages that Abi read on Thursday
= 35 x 1.8
= 63
(b)
Number of more pages that Abi read on Tuesday than on Thursday in percent
= 40% - 35%
= 5%
5% → 5 x 1.8 = 9
Number of more pages that Abi read on Tuesday than on Thursday = 9
Answer(s): (a) 63; (b) 9
