There were 27 more children in Group D than in Group E. If 10 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 + 27 |
1 u |
|
| Change |
- 10 |
+ 10 |
|
| After |
1 u + 17 |
1 u + 10 |
|
Number of children that Group D had after transferring to Group E
= 1 u + 27 - 10
= 1 u + 17
Number of children that Group E had after the transfer
= 1 u + 10
Number of children in Group D more than in Group E
= 17 - 10
= 7
Answer(s): 7
