Question

if I have 1 1/2 cups of spaghetti and 3/4 tsp of oregano to complete the dish, how much oregano do I need if only 1/2 cup spaghetti?

Answer 1

1 1/2 cups of spaghetti require 3/4 tsp of oregano to complete the dish.

How much oregano will be required for only 1/2 cup spaghetti?

We can set up the following proportion

`(1(1)/(2))/((3)/(4))=((1)/(2))/(x)`

Let us solve for x that is the tsp of oregano required.

`\begin{gathered} (1(1)/(2))/((3)/(4))=((1)/(2))/(x) \\ ((3)/(2))/((3)/(4))=((1)/(2))/(x) \\ (3)/(2)\cdot x=(1)/(2)\cdot(3)/(4) \\ (3)/(2)\cdot x=(3)/(8) \\ x=(3)/(8)\cdot(2)/(3) \\ x=(2)/(8) \\ x=(1)/(4) \end{gathered}`

Therefore, you will need 1/4 tsp of oregano.
