Comparing Hazel and
Nora at first |
30 more |

| Before |
15 u |
5 u |
| Change |
|
- 2 u |
| After |
15 u |
3 u |
Comparing Hazel and
Nora in the end |
5x3 =
15 u |
1x3 =
3 u |
Number of stickers that Nora had in the end is repeated. Make the number of stickers that Nora had in the end the same. LCM of 1 and 3 is 3.
Number of stickers that Hazel had at first = 15 u
Number of stickers that Hazel had more than Nora at first
= 15 u - 5 u
= 10 u
10 u = 30
1 u = 30 ÷ 10 = 3
Number of stickers that Nora had at first
= 5 u
= 5 x 3
= 15
Answer(s): 15
