Question

A pizzeria uses 5 oz of tomato sauce for every 4 oz of cheese. what two equations show the relationship between ounces of tomato sauce, x, and ounces of cheese, y?

Answer 1

In order to find the relationship between x and y, we can use a rule of three:

`\begin{gathered} 5\text{ oz of tomato sauce}\to4\text{ oz of cheese} \\ x\text{ oz of tomato sauce}\to y\text{ oz of cheese} \\ \\ 5y=4x \\ y=(4x)/(5) \\ (y)/(x)=(4)/(5) \end{gathered}`
