Hi Tianzhu,
I would like to know how to jump to know that 104 is multiplier of 4?

Hi, need help with this question:


Isaac was reading a book. On the first day, the number of pages he read was 2/5 of the number of pages unread. On the second day, he read another 24 pages of the book. As a result, the number of pages he read was 5/9 of the number of pages unread. If he had to complete reading the book in another 4 days, what was the average number of pages he had to read a day for the rest of the book?

Thanks!

My first reply seems to have gotten lost...

1st Day
Read : Not Read
2 : 5
4 : 10

2nd Day
Read : Not Read
5 : 9

(Equate the total of both days since total number of pages should be the same.)

5units - 4 units --> 24
9 units --> 24 x 9 = 216
216 ÷ 4 = 54

Hi Yu Xuan,

Very clear explanation! Thanks for your help!
