Jade had a story book with 450 pages. She read 50% 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% → 450
1% → 450 ÷ 100 = 4.5
Number of pages that Jade read on Thursday in percent
= 100% - 50% - 25%
= 25%
Number of pages that Jade read on Thursday
= 25 x 4.5
= 112.5
(b)
Number of more pages that Jade read on Tuesday than on Thursday in percent
= 50% - 25%
= 25%
25% → 25 x 4.5 = 112.5
Number of more pages that Jade read on Tuesday than on Thursday = 112.5
Answer(s): (a) 112.5; (b) 112.5
