Cameron has 4 clown fish in his fish tank. one third of the fish in the tank are clown fish. how many fish does cameron have in his tank?

describe how to draw a diagram to solve.

the denominator in 1/3 tells you that there are equal parts in the whole group. draw 3 circles to show equal parts.
since 4 fish are 1/3 of the whole group, draw counters in the first circle.
since there are counters in the first circle, draw counters in each of the remaining circles. then find the total number of counters.
so cameron has fish in his tank
