John and Yasmin's dad is named Gabriel. If John has twice the number of children that her sister has and Gabriel has six grandkids, how many children does Yasmin have?
A step-by-step solution is:
2
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.

The final answer: 2
