Answer 1

3

Explanation:

Answer 2

Sam will need 3 tablespoons of chili powder to make 1/2 the recipe.

Explanation:

We have to first find out out how many tablespoons of chili powder are needed for every liter of chili.

We know that 2/3 tablespoons make 1/9 liters of chili, therefore:

`(2/3\:tb)/(1/9\:liter) =(6\:tb)/(liter)`

So this is 6 tablespoons of chili powder per liter of chili.

Now if Sam's recipe is for 1 liter of chili, and he wants to make 1/2 the recipe, this means that Sam is making 1/2 liters of chili.

For 1/2 liters of chili we need

`(6\:tb)/(liter)*(1)/(2) lires= \boxed{3\:tablespoons.}`

So our answer is 3 tablespoons of chill powder.
