Karl is making a pot of chili. The recipe calls for StartFraction 3 Over 8 EndFraction cup of chili powder, but Karl only wants

mina [271]

Given:

The recipe calls for $\dfrac{3}{8}$ cup of chili powder.

Karl only wants to use half as much so it won’t be so spicy.

To find:

How much chili powder should Karl use?

Solution:

We have,

Chill power for recipe = $\dfrac{3}{8}$ cup

Chill power used by Karl is half of chill power for recipe.

$\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}$ cup $\text{Chill power used by Karl}=\dfrac{3}{16}$ cup

Therefore, $\dfrac{3}{16}$ cup of chili powder should Karl use.
