There were 28 more children in Group D than in Group E. If 9 children transferred from Group D to Group E, how many more children would be in Group D than in Group E?
|
Group D |
Group E |
|
Before |
1 u + 28 |
1 u |
|
Change |
- 9 |
+ 9 |
|
After |
1 u + 19 |
1 u + 9 |
|
Number of children that Group D had after transferring to Group E
= 1 u + 28 - 9
= 1 u + 19
Number of children that Group E had after the transfer
= 1 u + 9
Number of children in Group D more than in Group E
= 19 - 9
= 10
Answer(s): 10
