We don't know Yasmin's number of children yet, but let's represent it as Y. If John has twice the number of children Yasmin has, then John has 2 * Y = 2Y kids. If Gabriel has 6 grandkids between John's and Yasmin's children, then we can represent this as 6 = 2Y + Y. If we solve the latest equation then we learn that 6 = 3Y. Given that Y represents how many kids Yasmin has, then solving for Y we know that Y = 6 / 3 or Y = 2 kids.
Therefore, the answer is 2.
