x = 40/3

Step-by-step explanation:

We have to set up a proportion.

$\frac{12}{8} = \frac{20}{x}$

See that the diameter of the pizzas are both the numerators, and the ounces of dough are the denominators. We know the first pizza requires 8 ounces, but we don't know the second. The unknown variable will be x.

Solve the proportion by cross multiplying.

12(x) = 20(8)

12x = 160

Your answer is:

x = 13.3... or x = 40/3
