Question

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?
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.
