Anytime you want to show a fraction as a picture, the rule is as follows:
The numerator -- The number of things you want after you divide
The denominator - How many ways you want to divide.
Let's assume you have three PAYDAY candy bars. (I choose this because it's a six letter word - you can use whatever candy bar or food you wish.) We can divide the candy bars into six equal pieces. So the first candy bar is divided like below:
P - first part
A - second part
Y - third part
D - fourth part
A - fifth part
Y - sixth part
Now we can repeat the process for the other two candy bars. To keep things straight, I'll add a number to the pieces - 1, 2, 3 for the first, second, and third bar. Why 3? First, 18/6 simplifies to 3/1. That means there are three whole candy bars. Second, I chose a six letter candy bar because of the original number and 6 * 3 = 18. Our three candy bars (read it top down) look like the one above, and as such:
P1
A1
Y1
D1
A1
Y1
P2
A2
Y2
D2
A2
Y2
P3
A3
Y3
D3
A3
Y3
