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?

Answer 1

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

you set it up as a normal division problem then use KCF

keep the first term the same change the sign to a multiplication and flip the last term and use the inverse

Answer 2

Answer:

He should use $\frac{3}{16}$ cups of chili powder.

Step-by-step explanation:

Given,

The total quantity of chili powder = $\frac{3}{8}$ cups,

Also, only half of the chilli powder is used,

So, the used quantity of chilli powder = $\frac{1}{2}\times \frac{3}{8}$

$=\frac{3}{16}$  ( Multiplication of fractions ),

Hence, he should use $\frac{3}{16}$ cup of chili powder.
