Before |
5x4 = 20 u |
2 u |
Change |
- 4x4 = - 16 u |
- 1 u |
After |
1x4 = 4 u |
1 u |
Comparing Gabby and Parry in the end |
4 u |
1 u |
The number of candy canes that Gabby had in the end is repeated. Make the number of candy canes that Gabby had in the end the same. LCM of 1 and 4 is 4.
Number of candy canes that Gabby had more than Nora
= 20 u - 2 u
= 18 u
18 u = 36
1 u = 36 ÷ 18 = 2
Number of candy canes that Nora had at first
= 2 u
= 2 x 2
= 4
Answer(s): 4
