Seth had
38 the number of erasers that Jack had at first. After Jack gave Seth 27 of his erasers, Seth had
35 the number of erasers that Jack had. How many erasers did Jack have in the end?

Jack |
Total |
Before |
3x8 = 24 u |
8x8 = 64 u |
11x8 = 88 u |
Change |
+ 9 u |
- 9 u |
|
After |
3x11 = 33 u |
5x11 = 55 u |
8x11 = 88 u |
The total number of erasers that Seth and Jack had at first and in the end remains unchanged. Make the total number of erasers the same. LCM of 11 and 8 is 88.
Number of erasers that Jack gave Seth
= 33 u - 24 u
= 9 u
9 u = 27
1 u = 27 ÷ 9 = 3
Number of erasers that Jack had in the end
= 55 u
= 55 x 3
= 165
Answer(s): 165
