Kyle is 3 years old and the twins are 9

correct

Yes

To determine the ages of the twins, we need to find the difference between their age and Kyle's age.

The twins are 9 years old, and Kyle is 3 years old.

To find the age difference, subtract Kyle's age from the twins' age.

9 - 3 = 6

Therefore, the age difference between the twins and Kyle is 6 years.
