Karl is making a pot of chili. The recipe calls for StartFraction 3 Over 8 EndFraction cup of chili powder, but Karl only wants to use half as much so it won’t be so spicy. How much chili powder should Karl use?

Question

StartFraction 1 Over 16 EndFraction of a cup
StartFraction 1 Over 8 EndFraction of a cup
StartFraction 3 Over 16 EndFraction of a cup
Three-fourths of a cup

Answer 1

To find out how much chili powder Karl should use, we need to calculate half of the amount called for in the recipe, which is $\frac{3}{8}$ cup.

To find half of $\frac{3}{8}$, we can multiply it by $\frac{1}{2}$:

$$\frac{3}{8}\times \frac{1}{2}=\frac{3\times 1}{8\times 2}=\frac{3}{16}$$

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

The correct answer is $\frac{3}{16}$ of a cup.
