Yen and Jean had an equal number of stamps at first. Yen used
14 of her stamps and Jean used
19 of her stamps. They used 39 stamps altogether. How many stamps did Jean have in the end?

Yen |
Jean |
| Before |
4x9 =
36 u |
9x4 =
36 u |
| Change |
- 1x9 =
- 9 u |
- 1x4 =
- 4 u |
| After |
3x9 =
27 u |
8x4 =
32 u |
The number of stamps that Yen and Jean each had at first is the same. Make the number of stamps that Yen and Jean each had at first the same. LCM of 4 and 9 is 36.
Number of stamps that Yen and Jean used
= 9 u + 4 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Number of stamps that Jean had in the end
= 32 u
= 32 x 3
= 96
Answer(s): 96
