Natalie read
18 of the manuscript. If she had read another 207 pages, she would have read
710 of the whole manuscript altogether. How many pages were there in the manuscript?
|
Read |
Not read |
Total |
Before |
1x5 = 5 u |
7x5 = 35 u |
8x5 = 40 u |
Change |
+ 207 |
- 207 |
|
After |
7x4 = 28 u |
3x4 = 12 u |
10x4 = 40 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 8 and 10 is 40.
Number of additional pages that Natalie would have read
= 28 u - 5 u
= 23 u
23 u = 207
1 u = 207 ÷ 23 = 9
Number of pages in the manuscript
= 40 u
= 40 x 9
= 360
Answer(s): 360
