A tells you that the inner circle has 2/3 of the area of the outer circle. In C, forget for the moment how much of the entire thing has been shaded - can you now see how much of the shaded area is inside the inner circle as a proportion of the entire shaded area?

A =2/3 of the entire shape
C = 6/10 of the entire shape

What fraction of A is contained in C

A =2/3 of the entire shape
C = 6/10 of the entire shape

What fraction of A is contained in C

Would you just multiply them to find the overlap so 2/5?

That was my thinking, that it's 6/10 of 2/3
