Julian had
35 the number of erasers that Valen had at first. After Valen gave Julian 9 of his erasers, Julian had
34 the number of erasers that Valen had. How many erasers did Valen have in the end?

Total |
| Before |
3x7 =
21 u |
5x7 =
35 u |
8x7 =
56 u |
| Change |
+ 3 u |
- 3 u |
|
| After |
3x8 =
24 u |
4x8 =
32 u |
7x8 =
56 u |
The total number of erasers that Julian and Valen had at first and in the end remains unchanged. Make the total number of erasers the same. LCM of 8 and 7 is 56.
Number of erasers that Valen gave Julian
= 24 u - 21 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of erasers that Valen had in the end
= 32 u
= 32 x 3
= 96
Answer(s): 96
