16 of her stamps, Xylia had twice as many stamps as Gabby. How many stamps did Gabby have at first?

Comparing Xylia and
Gabby at first |

| Before |
10 u |
6 u |
| Change |
|
- 1 u |
| After |
10 u |
5 u |
Comparing Xylia and
Gabby in the end |
2x5 =
10 u |
1x5 =
5 u |
Number of stamps that Gabby had in the end is repeated. Make the number of stamps that Gabby had in the end the same. LCM of 1 and 5 is 5.
Number of stamps that Xylia had at first = 10 u
Number of stamps that Xylia had more than Gabby at first
= 10 u - 6 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Number of stamps that Gabby had at first
= 6 u
= 6 x 6
= 36
Answer(s): 36
